[comp.mail.sendmail] Problem with the Unix From line and Return-Path

tran@excelan.COM (Tony Tran) (10/03/89)

Hi there,

 I have been receiving a lot of mail message with the From line
 and Return-Path having our gateway hostname appended to it as follows:

>From @xlnvax.excelan.com:cratz@csibtfr.UUCP Thu Sep 28 17:16:50 1989
	  ^^^^^^^^^^^^^^^^^^^^
Return-Path: <@xlnvax.excelan.com:cratz@csibtfr.UUCP>
		   	  ^^^^^^^^^^^^^^^^^^^
 What I expect to see is a cleaner From line and Return-Path
  that has no local hostname attached to it (such as)

>From cratz@csibtfr.UUCP Thu Sep 28 17:16:50 1989
Return-Path: <cratz@csibtfr.UUCP>


Is it possible?

I have been playing around with the "n" flag to exclude the "From "
line, but it didn't help, because /bin/mail put it right back.

It appears that mail to the gateway machine has the correct
From line and the Return-path, but when the external mail got
forwarded to the local SUN machine, it seems to mess up the From line.

Also, does anybody know which rulesets control the address of
the cc: line?

Our gateway machine is running 5.61++/IDA patches. Its FQDN is
xlnvax.excelan.com. My local machine is a SUN 4/280 (SUN OS 4.0.1 
running Sun sendmail SMI-4.0).

Thanks in advance,
