Block Emails by their Subject

[Mandi]

I wish Plesk had more control over the Email Blocking!

At the moment I got thousands of emails with the same Subject from different IPs. Is there any way I can block these emails in a Plesk Server with Qmail?

There is no way to specify email subject to block such email messages.

But you may train and set up Spamassassin to delete all the spam emails.
Spamassassin uses special rules to detect spam message and you may create your own or upload any existent rules.

You may read more about available anti-spam options from the following articles:
