+ Fetch the hostname of the current system and put it in pine struct
+
+ Args: ps -- The pine structure to put the hostname, etc in
+
+ Result: hostname, localdomain, userdomain and maildomain are set
+
+
+** Pine uses the following set of names:
+ hostname - The fully-qualified hostname. Obtained with
+ gethostbyname() which reads /etc/hosts or does a DNS
+ lookup. This may be blank.
+ localdomain - The domain name without the host. Obtained from the
+ above hostname if it has a "." in it. Removes first
+ segment. If hostname has no "." in it then the hostname
+ is used. This may be blank.
+ userdomain - Explicitly configured domainname. This is read out of the
+ global pine.conf or user's .pinerc. The user's entry in the
+ .pinerc overrides.
+
+** Pine has the following uses for such names:
+
+ 1. On outgoing messages in the From: line
+ Uses userdomain if there is one. If not uses, uses
+ hostname unless Pine has been configured to use localdomain.
+
+ 2. When expanding/fully-qualifying unqualified addresses during
+ composition
+ (same as 1)
+
+ 3. When expanding/fully-qualifying unqualified addresses during
+ composition when a local entry in the password file exists for
+ name.
+ If no userdomain is given, then this lookup is always done
+ and the hostname is used unless Pine's been configured to
+ use the localdomain. If userdomain is defined, it is used,
+ but no local lookup is done. We can't assume users on the
+ local host are valid in the given domain (and, for simplicity,
+ have chosen to ignore the cases userdomain matches localdomain
+ or localhost). Setting user-lookup-even-if-domain-mismatch
+ feature will tell pine to override this behavior and perform
+ the local lookup anyway. The problem of a global "even-if"
+ set and a .pinerc-defined user-domain of something odd causing
+ the local lookup, but this will only effect the personal name,
+ and is not judged to be a significant problem.
+
+ 4. In determining if an address is that of the current pine user for
+ formatting index and filtering addresses when replying
+ If a userdomain is specified the address must match the
+ userdomain exactly. If a userdomain is not specified or the
+ userdomain is the same as the hostname or domainname, then
+ an address will be considered the users if it matches either
+ the domainname or the hostname. Of course, the userid must
+ match too.
+
+ 5. In Message ID's
+ The fully-qualified hostname is always users here.
+
+
+** Setting the domain names
+ To set the domain name for all Pine users on the system to be
+different from what Pine figures out from DNS, set the domain name in
+the "user-domain" variable in pine.conf. To set the domain name for an
+individual user, set the "user-domain" variable in his .pinerc.
+The .pinerc setting overrides any other setting.
