GNU Emacs mailer from error

[George Planansky]

On our covey of diskless Sun 3/60's, served by a Sun 3/280, Sun OS 4.0x,
mailings with the GNU Emacs ver. 18.52 mailer, put the wrong name in the
``From: username'' field.  

This occurs when mailing from a 3/60 login.  The letter arrives, saying it
came from that 3/60 and was received by the server, but the from: username
has the name of the recipient, not the sender.  If there is more than one
recipient, the first one named, shows up as the sender.  This occurs
whether or not the name of the recipient is an alias, possibly of several
names, or not.

If the bcc: field is filled with the name of the sender, then the from:
field has the correct value (I think).  If the from: field is filled
before sending the letter, the from: field and a sender: field both have
the correct, same, value.

When mailing from a server login, or from another machine (an Alliant,
currently choking on Concentrix 5.5.02 -- you can't rlogin anymore, e.g.,
but that's another story!), mail arrives with the correct from: field.

The Suns are using Yellow Pages, with the "real" ascii files being on the
server.

Mailings by the Sun OS mailer, by the Alliant's Concentrix mailer, and by
ELM on the Suns, have correct from: fields under all circumstances.

What's going wrong and how do I fix it?
