[Mailman-Users] Sendmail Milter subsystem telling sendmail to discard Mailman digests

[Jeff Groves]

OK, I have got to learn that when I get to the point where I ask for help, then it's time to 
just buckle-down and go to the next level of debugging.

Well, again, I have found the answer to my own post.  I'm sorry everyone.  After sending the 
message below, I disabled my milters one by one and lo and behold the milter that was causing 
the trouble was milter-date... actually, I think it's a bug in Mailman.  Regard the expanded 
log files from milter-date:

Feb  1 17:46:39 hoover milter-date[5534]: 00006 NOQUEUE: filterOpen(805d350, 
'localhost.localdomain', [127.0.0.1])
Feb  1 17:46:39 hoover milter-date[5534]: 00006 j11MkdZb005615: filterMail(805d350, 805e098) 
MAIL='<testlist-bounces at xxx.org>'
Feb  1 17:46:39 hoover milter-date[5534]: 00006 j11MkdZb005615: 
address='testlist-bounces at xxx.org' localleft='testlist-bounces' localright='' domain='xxx.org'
.
<extraneous stuff deleted for brevity>

Feb  1 17:46:40 hoover milter-date[5534]: 00006 j11MkdZb005615: filterRcpt(805d350, 805e098) 
RCPT='<jeffrey.groves at xxxx.com>'
Feb  1 17:46:41 hoover milter-date[5534]: 00006 j11MkdZb005615: reply 550 5.7.1 missing Date: 
header as required by RFC 2822 section 3.6
Feb  1 17:46:41 hoover sendmail[5615]: j11MkdZb005615: Milter: data, discard
Feb  1 17:46:41 hoover sendmail[5615]: j11MkdZb005615: discarded
Feb  1 17:46:41 hoover milter-date[5534]: 00006 NOQUEUE: filterClose(805d350)

As you can see, 4 lines from the end, milter-date is complaining that the email message does 
not have a RFC 2822 3.6 compliant Date: header.

Either this is a bug in milter-date or a bug in Mailman.  I can't tell from the resulting 
email message whether or not the Date: header was added by Mailman or by sendmail.  I'm going 
to have to have a Mailman guru check the digest mailer to see if it is including a Date: 
header or not and if so, what format it is using so that I can report the problem to the 
milter-date developer.

Again, sorry for answering my own posting again,
