+Further details on the Carmel driver and the modifications for
+the X-BWC-Glyph character set are under the doc directory.
+
+Building the Carmel driver
+--------------------------
+1. Build pine, the c-client and imapd as you would normally so
+ all machine dependent source directory links get set up correctly
+
+2. Copy all files from contrib/carmel/c-client into the Pine c-client
+ directory
+
+3. run "patch < Makefile.patch" to modify the Makefile.
+
+4. If you want the X-BWC-GLYPH character set stuff turned on in the
+ c-client for mail generated before 1994 make sure that
+ EXTRACFLAGS=-DBWC in the Makefile
+
+5. If you want the carmel driver to be the default for non-fully
+ qualified names, change that in the Makefile for your system.
+
+6. If you want the X-BWC-Glyph display code turned on some patches
+ have to be applied to Pine. If not, these steps can be skipped.
+ 6a. Copy all the files from carmel/pine into the pine source
+ directory.

+
+The "Carmel" mail format is cutsom mail file format that has messages
+saved in individual files and an index file that references them. It
+has also been called the "pod" or "vmail" format. This is probably not
+of interest to anyone away from it's origin, though the Carmel2 format
+might be.
+
+This driver reads and writes the format in conjunction with the carmel2
+driver. The carmel2 file driver does most of the work as most of the
+operations are done on the created auxiliary carmel2 index and the
+carmel index is updated when the mail file is closed.

+The Carmel2 mail file stores messages in individual files and
+implements folders or mailboxes with index files that contain
+references to the files a nd a full c-client envelope in an easily
+parsed form. It was written as a needed part of the pod mail file
+driver with hopes that it might be useful otherwise some day. It has
+only been run with the carmel driver.
+
+Advantages over Berkeley format and driver:
+ + Opening mail folder is very fast
+ + Expunge is fast
+ + Check point is very fast
+ + Memory usage is much lower
+ + Search of message headers is fast
+Disadvantages:
+ - Fetching a large message is slow
+ - Searching the message bodies is slow
+ - Sorting the mailbox is slow
+
+ Index File Format
+ -----------------
+
+The first line of the file is always:
+ "\254\312--CARMEL2-MAIL-FILE-INDEX--\n"
+
+It is followed by index entries which are of the format:
+---START-OF-MESSAGE---\007\001nnnnnnnnnn
+Ufrads______________________________
+Zxxxxxx
+D..... <Many fields here, labeled by the first letter in the line>
+ <Fields may be repeated>
+
+
+The index is almost an ASCII file. With the first version of this
+driver it is not advisable to edit this file, lest the byte counts get
+disrupted. In the future it will be editable. The file starts with
+two binary bytes so the file(1) utility will report it as "data" to
+discourage would be hackers from messing with it. The ^G is also in
+each index entry for the same reason. If you are reading this source you
+probably know enough to edit the index file without destroying it.
+Other parts of the format are designed for the easiest possible
+parsing. The idea was to have a file format that was reasonable to
+fiddle for debugging, to discourage inexperienced folks for fiddling
+it and to be efficient for use by the program.
+
+
+ Routines and data structures
+ ----------------------------
+
+C-CLIENT INTERFACE FUCTIONS
+ carmel2_valid - check to see if a mailbox is valid for carmel2 mail files
+ carmel2_isvalid - actual work of checking
+ carmel2_find - generate list of carmel2 mailboxes
+ carmel2_sift_files - select mailboxes out of list, used with scandir
+ carmel2_find_bboars - dummy routine, doesn't do anything
+
+ carmel2_open - initial phase of opening a mailbox
+ carmel2_open2 - real work of opening mailbox, shared with carmel driver
+ carmel2_close - close a mail stream
+
+ carmel2_fetchfast - fetch "fast" message info, noop for this driver
+ carmel2_fetchflags - fetch the flags, a noop for this driver
+ carmel2_fetchstructure - fetch and envelope and possibly body
+
+ carmel2_fetchheader - fetch the text header of the message
+ carmel2_fetchtext - fetch the text of the message (no header included)
+ carmel2_fetchbody - fetch the text of a body part of a message
+
+ carmel2_setflag - Set a flag for a message sequence
+ carmel2_clearflag - Clear a flag for a message sequence
+
+ carmel2_search - Invoke the search facilities
+
+ carmel2_ping - Check for new mail and see if still alive
+ carmel2_check - Checkpoint the message statuses to the disk
+ carmel2_expunge - Delete all the messages marked for delete
+
+ carmel2_copy - Copy a message to another mailbox
+ carmel2_move - Move a message to another mailbox
+
+ carmel_gc - Garbage collection, a noop for this driver
+ carmel_cache - The required c-client cache handler, doesn't do much
+
+ carmel2_append - Append a message to a mail folder
+
+SUPPORT FUNCTIONS
+ carmel_bodystruct - Fetch the body structure for a carmel message
+ carmel_parse_address - Parse the address out of a carmel index

+
+ carmel_readmsg - Read a message file into memory, header text or both
+ carmel_spool_mail - Get new mail out of spoold mail file
+ carmel_copy_msg_file - Make copy of messsage file when copying (unused)
+
+ carmel2_lock - Lock a carmel index for read or write
+ carmel2_unlock - Unlock a carmel index
+ carmel2_update_lock - Touch lock mod time, marking it as active
+ carmel2_bezerk_lock - Lock the spool mail file Berkeley style

+ carmel2_getflags - Turn the named flags into a bit mask
+ carmel_new_mc - Get pointer to new MESSAGECACHE, allocating if needed
+
+ carmel_append2 - The real work of append a message to a mailbox
+
+ carmel2_search-* - A bunch of search support routines
+
+ month_abbrev2 - Returns three letter month abbreviation given a name
+ carmel2_rfc822_date - Parse a date string, into MESSAGECACHE structure
+ carmel2_date2string - Generate a date string from MESSAGECACHE

+does read the headers in to create the Carmel2 index.) An estimate is
+made of the size needed to expand the file to convert the line ends

+doesn't fit, the whole buffer will be expanded by 50% and the whole
+read done over. When the header is read in a 30K buffer is allocated

+/*
+ * What? You want to understand the VALID macro anyway? Alright, since you
+ * insist. Actually, it isn't really all that difficult, provided that you
+ * take it step by step.
+ *
+ * Line 1 Validates that the 2-5th characters are ``rom ''.
+ * Line 2 Sets x to point to the end of the line.
+ * Lines 3-12 First checks to see if the line is at least 41 characters long.
+ * If so, it scans backwards up to 10 characters (the UUCP system
+ * name length limit due to old versions of UNIX) to find a space.
+ * If one is found, it backs up 12 characters from that point, and
+ * sees if the string from there is `` remote from''. If so, it
+ * sets x to that position. The ``|| T'' is there so the parse
+ * will still continue.
+ * Line 13 Makes sure that there are at least 27 characters in the line.
+ * Lines 14-17 Checks if the date/time ends with the year. If so, It sees if
+ * there is a colon 3 characters further back; this would mean
+ * that there is no timezone field and zn is set to 0 and ti is
+ * left in front of the year. If not, then it expects there to
+ * either to be a space four characters back for a three-letter
+ * timezone, or a space six characters back followed by a + or -
+ * for a numeric timezone. If a timezone is found, both zn and
+ * ti are the offset of the space immediately before it.
+ * Lines 18-20 Are the failure case for a date/time not ending with a year in
+ * line 14. If there is a space four characters back, it is a
+ * three-letter timezone; there must be a space for the year nine
+ * characters back. Otherwise, there must be a space six
+ * characters back and a + or - five characters back to indicate a
+ * numeric timezone and a space eleven characters back to indicate
+ * a year. zn and ti are set appropriately.
+ * Line 21 Make sure that the string before ti is of the form hh:mm or
+ * hh:mm:ss. There must be a colon three characters back, and a
+ * space six or nine characters back (depending upon whether or
+ * not the character six characters back is a colon). ti is set
+ * to be the offset of the space immediately before the time.
+ * Line 22 Make sure the string before ti is of the form www mmm dd.
+ * There must be a space three characters back (in front of the
+ * day), one seven characters back (in front of the month), and
+ * one eleven characters back (in front of the day of week).
+ *
+ * Why a macro? It gets invoked a *lot* in a tight loop. On some of the
+ * newer pipelined machines it is faster being open-coded than it would be if
+ * subroutines are called.
+ *
+ * Why does it scan backwards from the end of the line, instead of doing the
+ * much easier forward scan? There is no deterministic way to parse the
+ * ``user'' field, because it may contain unquoted spaces! Yes, I tested it to
+ * see if unquoted spaces were possible. They are, and I've encountered enough
+ * evil mail to be totally unwilling to trust that ``it will never happen''.

+
+- There are two locks. Plain locks and write locks. They are created
+ about the same way, but have different names. The time out on the write
+ locks is much shorter, because it should never be held for very long.
+
+- Hitching (links in file system) post locking is used so it will work
+ across NFS. Flock() could be used as it has two advantages. First it
+ is more efficient, second the locks will disolve automatically when the
+ process dies. The efficiency is not of great concern, and the
+ process should not (theoretically) die unless it crashes due to a bug
+ or it is abnormally terminated. The advantage of locking across NFS
+ is considered greater than the advantages of flock().
+
+- The mod time of the lock file is updated everytime mail_check()
+ or mail_ping() is called and the mod time on the lock file is recorded.
+ This is so it can be determined that the lock file is current.
+
+- When a read lock file over 30 or a write lock over 5 minutes old is
+ encountered it is assumed the lock is old and should be overridden
+ (because the process crashed or was killed).
+
+- Everytime the mod time on the lock file is updated (on calls to
+ mail_check() and mail_ping()), the mod time of the lock file is
+ checked against the record of what it was last set to. If the mod times
+ don't match the lock has been broken and overridden. Then the original
+ Pine should go into read-only mode.... This is only likely to happen if
+ someone suspends (^Z's) the process for more than 30 minutes, and another
+ process is started.

+Carmel driver notes
+-------------------
+Set folder-collections=#carmel#[] to configure Pine to use the
+carmel driver. You may include other colllections like a directory full
+of Berkeley mail folder
+
+
+
+Be sure you don't have a file called ".mailboxlist" in your home
+directory. If you do the list of mailboxes presented to be by
+the c-client will be out of that file rather than by querying each
+driver.
+
+If you have files in your home or mail directory, be sure they aren't
+called anything that starts with "#carmel#" or %carmel%. They will be
+incorrectly included by mail_find for the bezerk and other drivers.
+
+The carmel driver doesn't grab "inbox". This is to allow other drivers
+a shot at it. This may or may not work out in the long run. With the
+current version of Pine you must set your inbox-path=#carmel#inbox to
+cause the carmel inbox to be used.
+
+
+Patching/Compilation for Pine
+-----------------------------
+
+This set of files and patches was created for Pine 3.85 and the
+corresponding version 3.0 of the c-client and 7.63 of imapd. Hopefully
+they will continue to work with future versions of all of these. To
+apply the patches copy all the files in the subdirectories here (pine,
+c-client and imapd) to the corresponding directories in the Pine
+source. The run patch on each of the patch files and finally run the
+build script in Pine source root directory. This should result in a
+pine, pico and imapd binary in the bin directory ready to be
+installed. In the c-client directory there will be a bzk2cml binary
+for converting a Berkeley format mailbox to a Carmel format mailbox
+for the user running the program.
+
+The modifications to the Pine source are minimal. The two parts are
+the calls to link in the carmel driver, and the patches to display
+BWC-GLYPH text. Nearly all the patches are for the later. One
+additional patch is needed to specify the right driver for creating
+new mailboxes. This is currently a bit of a hack in Pine and will
+hopefully be fixed future versions of Pine. The patches to imapd are
+of exactly the same nature as those to Pine.
+
+If some of these patches fail, it's probably due to changes made in
+Pine (applying them to some other version than 3.85). In that cases
+the patches will have to be made manually.
+
+
+
+Fixed since the version of Sept '92.
+------------------------------------
+* Updated to conform with the changes in UW internal changes from
+ version 3.5X to 3.84. With these changes all the internal Pine calls
+ to the c-client are stabilized, possibly except some changes for
+ mail_create. This makes the carmel driver trivial to integrate with
+ future versions of Pine.
+
+* Driver now checkpoints both carmel and carmel2 indexes. This should
+ save the nightly from deleting mail that it shouldn't.
+
+* The driver only defaults messages without any content-type to
+ X-bwc-glyph instead of messages that were tagged text/plain. This will
+ cause the the glyph to richtext translations not to be applied when
+ the message already has a MIME header.
+
+* Some bug fixes to display of BWC-GLYPH text, including bug causing
+ periodic core dumps.
+
+* Handles case where data file for a message is missing properly
+
+* Bug fixes so critical code in driver is properly protected from
+ signals and interrupts.
+
+* Bzk2cml utility included to convert Berkeley mail folder into carmel
+ folders.
+
+* Fixed bug causing text of currently viewed message to be redisplayed
+ incorrectly after the arrival of new mail.
+
+* Carmel text served up by imapd is tagged type "plain" instead of
+ "X-bwc-glyph", though the text is not yet converted to richtext
+ and quoted-printable encoded like it should be to work with other
+ clients.
+
+
+Fixed in the Aug 1 version
+--------------------------
+* Only creates a maximum of four Carmel index backup files (COD.FUR files)
+
+* Folder listing now works with standard IMAP patterns
+
+* Carmel index is check-pointed on expunges
+
+* Carmel driver checks for new mail with folder name #carmel#inbox
+
+* New mail is incorporated on other than inbox
+
+* MIME decoding works properly now
+
+* Safer incorporation of new mail from /usr/spool/mail (carmel2 writes flushed)
+
+
+Fixed in Aug 23 version
+-----------------------
+
+* Fetchheader includes the separator so append will work
+
+* Fixed append to get size right and not insert random NULL's, \n's...
+
+* Conversion of glyph format to rich text in imapd
+
+
+Fixed in Aug 29 version
+-----------------------
+* Further fixes to append, including full locking
+
+* The #carmel#user#folder syntax now works properly
+
+* Further fixes to imapd to convert to richtext only when appropriate
+
+
+Fixed in Sep 2 version
+----------------------
+* Nearly complete conversion from glyph to richtext
+
+* Fixed bug causing lost new mail on quick in/out Pine sessions
+
+* A few related Pine bugs fixed: sorting, wrapping
+
+
+Fixed in Sep 25 version
+-----------------------
+
+* Recognizes all messages with subtype beginning with x-bwc-glyph as Glyph text.
+* Saves messages of type x-bwc-glyph-wide in files ending with .wid
+
+* When saving messages, the link is used rather than making a new file
+
+* Glyph messages after 1994 must have the x-bwc-glyph tag to be recognized
+
+* Bug fix to properly display '@' in glyph text
+
+* Incorporation of latest version of c-client (minor bug fixes)
+
+
+
+General Features
+----------------
+* The driver checks the MAIL environment variable for the place to
+look for new incoming mail for the "inbox".
+
+(There's a lot more than this, but it's not documented yet)

+
+Things fixed for Aug 31 version
+-------------------------------
+- fixed bug with 1994 cut off date for forcing Carmel mail to x-bwc-glyph
+- fixed bugs in text header searching
+- changed to new c-client way of looking up hostname
+- works with new c-client for remote creates with FQNs
+- now works with new c-client scheme for including new mail file drivers
+- integrated x-bwc-glyph stuff with Pine 3.90
++ (Fixed in by UW) Handles passwords for multiple imap servers/accounts
+- Implemented TRYCREATE protocol for IMAP copies and appends
+
+Previous fixes
+--------------
+- Better handling of case of full disk

+From tenser@snafu.eec.psu.edu Tue May 7 10:14:10 1996
+Date: Tue, 16 Apr 1996 14:57:45 -0000
+From: Dan Cross <tenser@snafu.eec.psu.edu>
+To: pine@cac.washington.edu
+Subject: Pine patches for the IBM RT (Pine 3.93, 4.3BSD)
+
+Hi there!
+ I ported pine 3.93 to the IBM RT running AOS using the BSD port. (AOS
+is IBM's port of 4.3BSD to the RT architecture.) There were only minor
+changes that had to be made to the source to get it running under AOS, so
+I just stuck with the BSD port. (It seemed like a waste to change, since
+there was so much duplication between the BSD port and an AOS port.)
+ I wanted to send back the patches to you all to get them re-integrated
+into the main distribution so that the RT becomes a supported architecture.
+So, without further inane babble by myself, here they are. Thanks!
+
+ - Dan C.
+
+(ps- if you would like my binaries to put up for FTP, let me know and I'll
+pack them up for ya'll!)

+ VMS readme for PINE/C-CLEINT/PICO
+ ========================
+
+Building
+========
+
+ There are three executables:
+Pico/PICO.EXE: This is the stand-alone version of the editor.
+C-Client/MTEST: Testing program for debugging purposes.
+Pine/PINE: The pine...
+
+In order to build SET DEF into the top directory (i.e. the one above PINE.DIR,
+PICO.DIR, etc.) and then @VMSBUILD. It will rename the C-CLient directory and
+then compile Pico, C-Client and Pine.
+
+Optional parameters to the VMSBUILD command:
+
+NETLIB - Use the Netlib library. It must be preloaded into [.NETLIB]NETLIB.OLB
+MULTINET - Call Multinet's transport directly.
+
+If more than one option is used - separate them with coma and no spaces.
+
+There are a few warnnings during the link - ignore them...
+On VAX we have to link the objects themselves and can't use libraries since the
+linker/librarian lose the global variables; on AXP it is ok...
+
+
+Using
+=====
+ All the user needs is the PINE.EXE; Pine reads the mail from the user's
+VMS/MAIL files and send outgoing mail either via mail routines using some
+foreign protocol or via direct SMTP to some SMTP server (I preffer this
+metod). You use the latter by defining SMTP-SERVER field with some host.
+If you do not set it you must define PINE_MAIL_PROTOCOL to the prefix of
+the foreign protocol used. For example, if you use SMTP% you have to define
+it to SMTP.
+ The global PINE configuration file (if needed) is located at UTIL$:PINE.CONF;
+if you want to recompile it with a different name then modify PINE/OS.H;
+
+
+Why TcpIp communication is needed?
+==================================
+ It is not really needed, but helps much. It is needed in three places:
+1. Sending mail: You can either send mail using the xxx% mechanism by defning
+ PINE_MAIL_PROTOCOL; in this case no TcpIp is needed.
+ you can use another mechanism: Don't define the above but set some SMTP
+ server node name in PINE.CONF or .PINERC. In this case you need some
+ SMTP package.
+2. PINE can read NEWS via the NNTP protocol which runs over TcpIp...
+3. Remote nodes (usually PC) can access the IMAP daemon and PINE can access
+ remote IMAP servers using TcpIp.
+
+
+Restrictions
+============
+1. In order to not modify the source too much the handling of the special
+ INBOX folder was not modified. Hence, it always try to open the (empty)
+ INBOX folder instead of NEWMAIL.
+ It is possible to define in the system's wide PINE.CONF that
+ inbox-path=NEWMAIL. In this case NEWMAIL will be opened when PINE is
+ started. However, the user must not then switch to another folder as long
+ as NEWMAIL has items.
+2. WASTEBASKET folder is not used.
+3. .PINERC and .ADDRBOOK are fixed to the user's login directory and cannot
+ be defined to be elsewhere (the definition is ignored).
+4-100. Probably exists and I forgot to mention :-)
+
+
+IMAPD
+=====
+ IMAPD of version 3.89 is available with the old Pine VMS port from
+VMS.HUJI.AC.IL; the current version of IMAPD will be ported soon.
+
+
+NETLIB
+======
+ NETLIB can be obtained from PUBLIC.TGV.COM:/MADISON/NETLIB. NETLIB supports
+all the common TcpIp packages like Multinet, UCX, Fusion, Wollongong, etc.
+
+
+Suggested PINE.CONF file.
+=========================
+here is the PINE.CONF file we use here:
+
+# Our fully-qualified machine name:
+user-domain=vms.huji.ac.il
+
+# Where to connect to send outputgoing mail.
+smtp-server=vms.huji.ac.il
+
+# Which viewer to see GIF/JPEG/etc.
+image-viewer=xv
+
+# Which folder will be opened automatically when entering PINE. See note above.
+inbox-path=NEWMAIL
+
+
+Notes:
+=====
+1. Due to the readonly definition in the source files we use an external
+ #define to redefine it to something else. Due to that CTYPE.H fails, so
+ we use a private copy of it.

+S/MIME capabilities in Pine
+
+Patch Author: Jonathan Paisley
+Contact Info: paisleyj@dcs.gla.ac.uk
+WWW: http://www.dcs.gla.ac.uk/~paisleyj/
+
+This patch adds S/MIME functionality to Pine. It was
+last tested thoroughly with Pine 4.33, and it has been updated
+to work with the latest version (4.52).
+
+Check out the unix 'patch' command. An example of using
+patch would be:
+
+$ cd ../.. # Change to top level directory (containing contrib, pine, etc)
+$ patch -p1 < contrib/smime/pine-smime-151101.diff
+
+*** After patching, read pine/README.smime for more details. ***

+
+Note that this patch has only been tested on Solaris and Linux (thus only
+those makefiles have been patched). The changes that have been made to
+the makefiles are as follows:
+
+ Add these SSL variables (these were roughly lifted from imap/src/osdep/unix/Makefile)
+
+ SSLDIR= $(HOME)/local/ssl
+ SSLCERTS= $(SSLDIR)/certs
+ SSLINCLUDE= $(SSLDIR)/include
+ SSLLIB= $(SSLDIR)/lib
+
+ SSLCFLAGS= -I$(SSLINCLUDE) \
+ -DSSL_CERT_DIRECTORY=\"$(SSLCERTS)\" \
+ -DSMIME
+ SSLLDFLAGS= -L$(SSLLIB) -lcrypto
+
+ Add $(SSLLDFLAGS) to the LIBS variable.
+ Add $(SSLCFLAGS) to the CFLAGS variable.
+ Add bss_so.o smime.o smkeys.o to the OFILES= variable.
+
+Similar changes would have to be made to the makefile for other ports.

++ Quick Start
++ ===========
++
++ To enable S/MIME support, ensure the SSL related lines in the platform
++ makefile are uncommented (they're all next to one another).
++
++ CA certificates are expected to be found in the OpenSSL 'cert' dir, in the
++ standard hashed format.
++
++ User Configuration
++ ==================
++
++ A directory '~/.pine-smime' must be created. Within this, a further
++ three directories are required:
++
++ ~/.pine-smime/
++ ca/
++ private/
++ public/
++
++ Other people's certificate files should be copied into the 'public' directory.
++ Your certificate file(s) should be copied into the 'private' directory.
++ Certificates for any additional trusted CAs should be put in the 'ca' directory.
++
++ There are three extra configuration options:
++
++ sign-default-on
++ encrypt-default-on
++ remember-smime-passphrase
++
++ Certificates
++ ============
++
++ The certificate files specified above should have the following form:
++
++ public certificates: user@emaildomain.crt
++ private keys: user@emaildomain.key
++
++ Thus, a typical installation might look like this:
++
++ ~/.pine-smime/
++ ca/
++ [additional trusted CAs here]
++ private/
++ paisleyj@dcs.gla.ac.uk.crt
++ paisleyj@dcs.gla.ac.uk.key
++ public/
++ myfriend@dcs.gla.ac.uk.crt
++ myotherfriend@dcs.gla.ac.uk.crt
++
++ Implementation Details
++ ======================
++
++ Link with the OpenSSL crypto library for PKCS7 support.
++ Only tested on linux (slx) and solaris (so5).
++
++ Added three extra source files (+headers):
++
++ smime.c Main S/MIME support code
++ smkeys.c Very basic X509 key handling/storage (using the above dirs)
++ bss_so.c OpenSSL BIO using pine STORE_S objects
++
++ Patches to existing pine sources:
++
++ init.c
++ Add references to new configuration options.
++
++ mailcmd.c
++ Add implementation of MC_DECRYPT command which prompts
++ the user for a passphrase if it's required.
++
++ mailpart.c
++ Comment added to help me remember what I'd done.
++
++ mailview.c
++ Added description of Decrypt menu option.
++ Make calls out to smime.c functions to handle the decryption.
++ This is done shortly after the BODY of a message is
++ obtained.
++ Added function to describe encrypted messages when they're
++ being displayed.
++ Added code to describe the special case of PKCS7 attachments.
++
++ makefile.lnx
++ makefile.so5
++ Added SSL variables etc.
++
++ pine.h
++ Add enumerations for new configuration options and definition
++ of MC_DECRYPT command
++ Exported the prototype of pine_write_body_header,
++ pine_rfc822_output_body and pine_encode_body since they're
++ needed in smime.c.
++
++ pine.hlp
++ Added help info for new configuration options.
++
++ send.c
++ Added 'Encrypt' and 'Sign' menu options when sending email.
++ Make calls to smime.c functions to fiddle message on the
++ way out.
++ Extend pine_encode_body so it makes a few more checks
++ before adding a boundary.
++
++ Basic method:
++
++ Incoming
++
++ Scan BODY of viewed message before it is formatted. If it contains
++ PKCS7 parts, decode them and attempt to decrypt/verify signatures. The
++ original BODY is fiddled in place and turned into a multipart body
++ with one subpart -- the decrypted data. This may consist of a multipart
++ with attachments, for example.
++
++ This all depends on stashing a pointer to the decrypted data in
++ body->contents.text.data and relying on the fact that the mail_* routines
++ will use this data in preference to fetching it over the network. We
++ also depend on it not being garbage collected while the message is
++ being viewed!
++
++ Outgoing
++
++ smime.c pre-builds the message using pine_encode_body, pine_write_body_header
++ and pine_rfc822_output_body, encrypting/signing the resulting data. The
++ body that was going to be sent is then fiddled appropriately after
++ the PKCS7 objects have been built.

+This would be a nice suggestion for Pine, however, you can do pretty much
+the same in Unix using the following awk script. Copy everything between the
+lines into a file named: everyone
+
+-------------%< clip --------------
+{
+ printf("everyone\tEveryone\t(");
+
+ if ( $0 ~ /\(/ )
+ continue
+ else
+ printf("%s", $1);
+
+ while ( getline > 0 ) {
+ if ( $0 ~ /\(/ )
+ continue
+ else
+ printf(",%s", $1);
+ }
+ printf(")\n");
+}
+-------------%< clip --------------
+
+Now, type the following exactly at the Unix prompt:
+
+awk -f everyone < ~/.addressbook >> ~/.addressbook && echo Done.
+
+You may wish to first copy your ~/.addressbook file to a backup file,
+before executing this command.
+
+If everything went well, it should say Done. When you start Pine, there
+should now be a list in your address book with the name: everyone,
+containing all of your address book nicknames (but NOT other lists).
