Troubleshooting Mailman Mailing List Manager

Mailman under Plesk provides comprehensive logging which can be useful when troubleshooting mailing list problems.

Check the maillog itself:

• /usr/local/psa/var/log/maillog

You can find the mailman logs here:

• Bounce log: /var/log/mailman/bounce
• SMTP failure log: /var/log/mailman/smtp-failure

When using Mailman on Plesk, ensure to have 127.0.0.1 in your Tools & Settings > Mail Settings > White List to avoid SMTP Auth problems.

Using Spamdyke and Qmail to Stop Outgoing SPAM

These applications work together well but there is a loophole which can be closed as follows.

First, we force require-auth in spamdyke.conf, add this line to the top:

filter-level=require-auth

On its own this will not work properly and will block incoming mail from external providers. So, we need to dynamically create a whitelist that spamdyke can work with. We use a PHP script as follows:

<download php script>

Run this script as a cronjob every 15 minutes to gather updated email address from Plesk.

Now you will see that the spam email that has been finding its way through the loopholes can now no longer send emails. You can check the blocked emails using this rule as follows:

cat /var/log/maillog | grep "DENIED_AUTH_REQUIRED"

See how emails from ebay, paypal etc are no longer being sent from compromised accounts?

Your new Plesk 12 Dedicated Server will need to have the PHP.INI Timezone set for both PHP and Roundcube.

You need to edit:

nano /etc/php.ini
nano /etc/psa-webmail/roundcube/php.ini

Enter/update the timezone information as below:

date.timezone = Europe/London

Use the correct region for your location.
