[mlmmj] Configuration problems using mlmmj+postfix

[Christian Gleerup]

Hi List,

I have migrated to a new server, and have done a reconfiguration of mlmmj, the old installation was kind of the same, but not following best practice. 
I have configured following the documentation here: http://mlmmj.org/docs/readme-postfix/

But I have some problems getting mlmmj to send mails out, and I don't know where to look, so I hope you can help me.

I have the following clues
In /var/log/mail.err
Nov 23 16:00:01 Lists /usr/local/bin/mlmmj-send[21648]: init_sockfd.c:56: Could not connect to 127.0.0.1: Connection refused

I have set up the transport in postfix as recommended, and the transport files are owned by the root, with read access to multiple users
root@lists:/var/spool/mlmmj# ls -la
total 44
drwxr-xr-x  3 mlmmj mlmmj  4096 Nov  9 21:12 .
drwxr-xr-x  7 root  root   4096 Nov  9 20:22 ..
drwxr-xr-x 13 mlmmj mlmmj  4096 Nov 23 16:00 nyhedsbrev
-rw-r--r--  1 root  root     90 Nov  9 21:11 transport
-rw-r--r--  1 root  root  12288 Nov  9 21:12 transport.db
-rw-r--r--  1 root  root     82 Nov  9 21:09 virtual
-rw-r--r--  1 root  root  12288 Nov  9 21:12 virtual.db

In /var/spool/mlmmj/transport
# for a flat structure
lists.[my-tld]--nyhedsbrev@localhost.mlmmj   mlmmj:nyhedsbrev

In /var/spool/mlmmj/virtual
nyhedsbrev@lists.[my.tld]    lists.[my.tld]--nyhedsbrev@localhost.mlmmj

I am able to subscribe, unsubscribe and wiev the subscribers from the web interface, I do this in the following way
sudo -u mlmmj /usr/local/bin/mlmmj-sub ...
sudo -u mlmmj /usr/local/bin/mlmmj-unsub ...
sudo -u mlmmj /usr/local/bin/mlmmj-list ...
this works fine, ofcourse the relavent stuff is configured for sudoers.

If needed I will post main.cf and master.cf from postfix.

Kind regards
Christian Gleerup

By default mlmmj uses 127.0.0.1 as relay host, when sending mails. It
appears that you don't have an SMTP server listening there.

Does the following command (assuming you're on Linux) show an SMTP
daemon?

$ netstat -nltp

Kind regards,
Morten

I had a quick look at the code, are you sure you are not overriding the
port in the control/smtpport setting for your list? Also, there's
a "secret" MLMMJ_TESTING environment variable which overrrides the port
to 10025 :-)

So, Postfix *is* listening on TCP/25. Can you telnet to 127.0.0.1 25 ?

Kind regards,
Morten

Yes, and you can do that by just removing the "smtpport" file.

The command line is fine.

Ideas:

See if you can submit a mail using /usr/sbin/sendmail which is delivered to Mlmmj 
or not. If that doesn't work, something is wrong with the Postfix configuration.

Then check further outwards. Are you firewalled? Is Postfix listening on external 
interfaces, or loopback only? Can you connect to port 25 of the server with telnet 
externally?

You could create a test mailing list, with the same configuration as
your newsletter list, but with only you as a subscriber. That would
allow you to test Ben's suggestions, without risk of delivering test
newsletters to your subscribers.

Kind regards,
Morten
