Dear Ben,

thanks for listening and following up! I am happy to contribute to finding the root cause of this (potential) issue.

Here is a quick overview of what I have:

FreeBSD 10.1 (AMD64)
Postfix 3.1.0
mlmmj 1.2.17.1

So overall, pretty standard and nothing extraordinary I would say. Here is an overview of my config (basically taken from http://mlmmj.org/docs/readme-postfix/):

—

1) Create mlmmi user
# id mlmmj
uid=1021(mlmmj) gid=1021(mlmmj) groups=1021(mlmmi)

2) Create home dir and give it to mlmmi user

# ls -la /var/spool
(…)
drwxr-xr-x  33 mlmmj  mlmmj   45 21 Okt 22:38 mlmmj

3) Amend configuration of Postfix's master.cf

# grep mlmmj /etc/postfix/master.cf
# mlmmj mailing lists
mlmmj   unix  -       n       n       -       -       pipe
   flags=DORhu user=mlmmj argv=/usr/local/bin/mlmmj-recieve -F -L /var/spool/mlmmj/$nexthop

4) Amend main.cf of Postfix

# grep mlmmj /etc/postfix/main.cf
virtual_alias_maps = hash:/etc/postfix/virtual,hash:/var/spool/mlmmj/virtual,mysql:/etc/postfix/mysql_virtual_alias_maps.cf
transport_maps = regexp:/etc/postfix/transport,hash:/var/spool/mlmmj/transport
mlmmj_destination_recipient_limit = 1
recipient_delimiter = +

5) Create file system structure for mailing list (flat file structure):

# ls -la /var/spool/mlmmj/newsletter
total 77
drwxr-xr-x  15 mlmmj  mlmmj    17  8 Nov 15:14 .
drwxr-xr-x  33 mlmmj  mlmmj    45 21 Okt 22:38 ..
drwxr-xr-x   2 mlmmj  mlmmj    14 11 Jan 18:06 archive
drwxr-xr-x   2 mlmmj  mlmmj   140  4 Mär 22:04 bounce
drwxr-xr-x   2 mlmmj  mlmmj     7 28 Sep 22:39 control
drwxr-xr-x   2 mlmmj  mlmmj     2  7 Sep  2015 digesters.d
drwxr-xr-x   2 mlmmj  mlmmj     2 10 Mär 21:26 incoming
-rw-r--r--   1 mlmmj  mlmmj     2  4 Mär 21:33 index
-rw-------   1 mlmmj  mlmmj  1234  4 Mär 21:33 mlmmj.operation.log
drwxr-xr-x   2 mlmmj  mlmmj    12 10 Mär 21:26 moderation
drwxr-xr-x   2 mlmmj  mlmmj     2  7 Sep  2015 nomailsubs.d
drwxr-xr-x   3 mlmmj  mlmmj     3 10 Mär 21:26 queue
drwxr-xr-x   2 mlmmj  mlmmj     2  7 Sep  2015 requeue
drwxr-xr-x   2 mlmmj  mlmmj     2  7 Sep  2015 subconf
drwxr-xr-x   2 mlmmj  mlmmj    27  7 Mär 06:13 subscribers.d
drwxr-xr-x   2 mlmmj  mlmmj    36  7 Sep  2015 text
drwxr-xr-x   2 mlmmj  mlmmj     2  7 Sep  2015 unsubconf

Note: In the operation.log there is nothing to suggest why the mailing list is malfunctioning sometimes.

6) Creation/amendment of transport and virtual file for mlmmj and Postfix integration:

# grep newsletter /var/spool/mlmmj/transport
[email protected]   mlmmj:newsletter

# grep newsletter /var/spool/mlmmj/virtual
[email protected]    [email protected]

7) Postmapping and then postfix restart

# postmap /var/spool/mlmmj/virtual
# postmap /var/spool/mlmmj/transport
# postfix reload

--

First question: I assume the config is correct, right?

Secondly, yes I checked all file permissions and they should be fine too.

Now the question is: How can I best troubleshoot the issue? Any further suggestions on where to look for a root cause? My mail logs did not really contain any further information.

Many thanks.

Best regards
Sebastian
