After some frenzied finger pointing in the direction of sendmail, it
looks like there is some sort of bug in elm 2.3 PL11 that creatively
rewrites return addresses. The best way of describing what happens is by
practical example:
This is an experiment for you to perform. In between the cut here lines
is a message file - please extract it, knock out the leading # (inserted
just in case something funny happens in transit) and stick the result in
a little test elm ~/Mail folder. Climb into elm, change to this folder
and do a group reply to the message. Instead of sending it (:-), edit
the headers and take careful note of what the cc: addresses have turned
into...... (please, oh please use 'f' and not 's' when the experiment is
complete).

Now, climb back into the folder and edit the From: frcs!paul to be
From: paul@frcs and repeat the process. Have a look at the generated
cc: headers from the 'g'roup reply. Look any better? You bet....
OK, whats going on here? Explanations invited! Enquiring minds are enquiring!

The experiment included with the original posting here did some unusual things; things I would not expect an RFC complient mailer to do. Any comments on whether this is the intended actions of elm? -- dean@coplex.UUCP Dean A. Brooks Copper Electronics, Inc. Louisville, Ky UUCP: !uunet!coplex!dean
