I have just started to fight with Spam mails because of my new project. I will explain structure of that system.
We have Postfix as MTA on relay server and fresh Spamassasian and Policyd(v2 Cluebringer) add-ons for it. These are working well and they generate good outputs in log files.
My Question in this schema,how I can learn which add-on is working first?
Why I want to learn this:
- If Policyd is reject mails because being not real mail address Spamassasian will not work and system will not work to scan all mails
- If I install Clamav, it will not use so much resources
Best Regards.
