[Mailman-Users] Not all mail getting delivered

[Ryan Verner]

Howdy,

I configured mailman ages ago on a client's system; the lists are 
designed for things such as newsletters and news updates, and only he's 
allowed to post.  Mailman is configured accordingly, and indeed, things 
(mostly) work.

As I migrated away from an old server running majordomo, I imported a 
whole bunch of addresses.  Most of the subscribed addresses (and 
there's hundreds) are mail accounts on the local system, but some are 
external.

The problem is that a very large amount of the subscribed addresses are 
of old users, and don't exist anymore.

What happens is so many emails get delivered, then it just stops; I was 
using an older version of Mailman, I upgraded this to the latest 
(2.1.4), which I thought fixed the problem (it started delivering held 
mail from months back), but apparently there's still a reasonable 
percentage of users that aren't getting mail.

In the logs, he's seeing things such as (which he believes is related 
to Mailman):

Apr  9 09:59:54 server postfix/smtpd[28145]: too many errors after RCPT 
from
server[127.0.0.1]
Apr  9 09:59:54 server postfix/smtpd[28145]: disconnect from
server[127.0.0.1]

I've insisted the guy should go in and manually clean up the subscriber 
list, but he says majordomo handled this fine, and so should mailman.  
(I thought mailman did?).

The MTA used locally is postfix.  I've tried tweaking various things in 
it, such as disabling the guy's super paranoid anti-spam stuff [which 
was causing some issues, but not this], but to no avail.

This is a Debian Woody system.  Initially I was running the woody 
version of Mailman, but now I'm using a 2.1.4 backport (@ 
http://www.qbalt.com/debian/woody).

I'm using the same backport on several other systems, and have no such 
problems; I don't have so many invalid email addresses in my subscriber 
list, though.

Does anybody have any ideas?  This is somewhat hard for me to debug for 
several reasons, and the problem is a little erratic.  I'm hoping 
people can make decent suggestions on where to look, and maybe this is 
a well known issue that's easily fixed.

Cheers,

R
