* SMIME: Bouncing could sign (and therefore corrupt) a message when it
is signed automatically. Reported by Björn Krellner.

To strike this - balance, we have tried to adhere to these design principles: - - - The model presented to the user has to be simple and clear. - Underlying system operation is hidden as much as possible. - - It's better to have a few easily understood commands that can - be repeated than to have some more sophisticated command that - will do the job all at once. - - Whenever the user has to select a command, file name, address, - etc., the user should be given (or can get) a menu from which to - make the selection. Menus need to be complete, small, organized - and well thought out. - - _Alpine_ must provide immediate feedback for the user with - each operation. - - _Alpine_ must be very tolerant of user errors. Any time a user - is about to perform an irreversible act (send a message, expunge - messages from a folder), _Alpine_ should ask for confirmation. - - Users should be able to learn by exploration without fear of - doing anything wrong. This is an important feature so the user - can get started quickly without reading any manuals and so fewer - manuals are required. - - The core set of _Alpine_ functions should be kept to a minimum - so new users don't feel "lost" in seemingly extraneous commands - and concepts. - - Just as there were goals relating to the look and feel of _Alpine_, - there were equally important goals having to do with _Alpine_'s - structure-the things that users never see but still rely on every time - they use _Alpine_. While _Alpine_ can be used as a stand-alone mail - user agent, one of its strongest assets is its use of the Internet - Message Access Protocol (IMAP) for accessing remote email folders. In - addition, _Pine_ (the predecessor of _Alpine_) was one of the first - programs to support the Multipurpose Internet Mail Extensions (MIME) - specification. With MIME, _Alpine_ users can reliably send any binary - file to any other person on the Internet who uses a MIME compliant - email program. - - The decision to use IMAP and MIME reflects the importance of - interoperability, standardization and robustness in _Alpine_. As you - work with _Alpine_ more, you will see other features which reflect the - same values. For example, _Alpine_ enforces strict compliance with RFC - 2822, implements a strong mail folder locking mechanism and verifies a - process before overwriting any files (e.g. addressbook, expunging - messages). - -Alpine Components - - If you have picked up the _Alpine_ distribution, then you already know - that _Alpine_ comes in a few different pieces. They are: - - _Alpine_ - The main code from which the _Alpine_ program is compiled. - _Pico_ - _Pico_ is the name for the _Alpine_ composer. The _Pico_ code is - used in two ways: (1) it is compiled on its own to be a - stand-alone editor and, (2) it is compiled as a library for - _Alpine_ to support composition of messages within _Alpine_. - _Pico_ is _Alpine_'s internal editor invoked when users need to - fill in header lines or type the text of an email message. - _Imap_ - An API for IMAP. Includes the C-Client library, which is - compiled into _Alpine_, and the IMAP server _IMAPd_. C-Client - implements the IMAP protocol and also negotiates all access - between _Alpine_ and the mail folders it operates on, even if - the folders are local. The C-Client routines are used for email - folder parsing and interpreting MIME messages. _IMAPd_ is a - separate server that handles IMAP connections from any - IMAP-compliant email program. When _Alpine_ accesses a remote - mailbox, the _Alpine_ program is the IMAP client and the _IMAPd_ - program is the IMAP server. Of course, _Alpine_ can use any - IMAP-compliant IMAP server, not just _IMAPd_. - Background Details Domain Names |
