I have the following setup:

Postfix -> Dspam -> Procmail -> Mailman -> Users

I've tried taking Dspam out of the equation, but that did not change a thing.

When users send to a mailing list, the message appears to be deilvered to mailman.
However, mailman does not do anything afterwards: i.e. its does not send the
messages to the users.

qrunner is running. I traced the problem to the following:

In logs/post I saw this:

Aug 19 02:01:09 2007 (15427) post to list from falko at reservoir.com, size15, message-id=<20070819054804.GC14916 at reservoir.com>, 12 failures
Aug 19 02:01:09 2007 (15428) post to list from falko at reservoir.com, size15, message-id=<20070819054804.GC14916 at reservoir.com>, 12 failures

The message is repeated more than 12 times.

And what is in the smtp-failure log?
This stuff:

Aug 19 13:09:18 2007 (7258) delivery to addr1 at reservoir.com failed with code -1: (111, 'Connection refused')
Aug 19 13:09:18 2007 (7258) delivery to addr2 at reservoir.com failed with code -1: (111, 'Connection refused')
Aug 19 13:09:18 2007 (7258) delivery to addr... at reservoir.com failed with code -1: (111, 'Connection refused')

So the question I guess is, why is postfix refusing the connnection? How does mailman connect to
postfix?

I am using this in mm_cfg.py:

# Maildir
USE_MAILDIR = Yes
QRUNNERS.append(('MaildirRunner', 1))

DEFAULT_DIGESTABLE = No

# Uses genaliases as covered by mailman docs.
MTA = 'Postfix'


In /etc/postfix/main.cf I have this:

alias_maps = hash:/etc/aliases, hash:/var/lib/mailman/data/aliases

Inside /var/lib/mailman/data/aliases:

# STANZA START: list
# CREATED: Sun Aug 19 01:13:18 2007
list: /var/lib/mailman/qfiles/maildir/

# STANZA END: list
In logs/error I see this:

There is a bug in check_perms. It does not check for sufficient access
to archives/private/ - permissions should be at least drwxrws--- and
group mailman.

This too looks like multiple qrunners processing the same queue slice.


<snip>
I have run bin/check_perms multiple times, but it tells me that there are no problems.

See above.
