S : SendMail

Hi,

I have an annoying problem with Sendmail 8.13; not sure if it's
present in 8.14.

I'm running the equivalent of this:

sendmail -odd -oi -Ac -fsomeone@example.net recipient@example.net <<EOF
From: <someone@example.net>
To: <recipient@example.net>
Cc: <unbalanced1@example.net, <unbalanced2@example.net
Subject: A message

Message text here.
EOF

Notice the unbalanced angle brackets on the Cc: line?

(Please don't ask *why* I'm trying to submit such a message locally;
just trust me when I say there's a valid reason for it. I'll happily
discuss it at length off-list.)

The problem is that during the client queue run, Sendmail gets upset
at the unbalanced addresses in the Cc: line and generates DSNs. I
don't want that! I don't want Sendmail to give a hoot about the
headers; I only want it to worry about envelope addresses.

In my limited testing, Sendmail 8.14 seems to work, but Sendmail 8.13
does not. For various reasons, it's difficult to move some of our
customers to Sendmail 8.14, so is there a way in Sendmail 8.13 to suppress
the DSNs?

Regards,

David.

I found some deep voodoo that solved the problem. The original submit.mc
file had this line in it:

define(`confDIRECT_SUBMISSION_MODIFIERS', `C')dnl

Commenting that out and rebuilding submit.cf made the problem go away.
This is a real WTF??? moment for me; after trolling in the Sendmail source
code for a couple of hours, I think I'm about ready to learn Postfix.

David.

It is no longer "wise" to use sendmail *only* because you do not know
available (free) alternatives :-)
