Subject:   Sendmail header substitution
Message-ID:  <86it24w1bv.fsf@jamestown.21stcentury.net>

My problem is this: After upgrading to 4.6, the new sendmail
configuration keeps substituting `localhost' for the host name in
email headers. This is causing the two nodes on my private network to
reject each other's mail.

Since I have root on my headless firewall/print server aliased to my
user account on my workstation, I can't get the output of periodic
scripts as I normally did.

This shows up in the sending hosts mail log:

    Aug 21 03:03:57 tater sendmail[10550]: g7L83q7f010548:
    to=jtm@jamestown, ctladdr=<root@tater.21stcentury.net> (0/0),
    delay=00:00:03, xdelay=00:00:01, mailer=esmtp, pri=33954,
    relay=jamestown.21stcentury.net. [192.168.1.1], dsn=5.6.0,
    stat=Data format error

And I eventually get a message (after bouncing around some between
machines) that includes:

----BEGIN PART OF ERROR MESSAGE----

The original message was received at Wed, 21 Aug 2002 09:00:14 -0500 (CDT)

----END PART OF ERROR MESSAGE----

Somewhere in the configuration files now, localhost.$m is being
substituted for $j in the headers and the recieving MTA is refusing to
accept the message because it thinks itself to be localhost (and it
is right!). I don't see why you would do this, but I would like to
turn it off. However, I still haven't found a way.

Any one know what happened and how to fix it?

Jim
