Topic: Spam has become a problem. Ideas on how I can tighten my config?

Hello Everyone,

I'm having a problem with spam and need some ideas on how I might address it. I have iRedMail configured with its default config EXCEPT I'm disabled the rejecting invalid EHELO's since that was causing a problem with cross-domain email. But even when I turn this back on, spam still pours in. It really is like nothing is being caught.

Now, I will say that I have only one 'real' email address configured and all the others are aliases. Could this be the problem? Most of the spam seems to be coming in from the aliases and not being caught.

Thoughts?

Thanks!
Anthony

You can try to use DNS RBL services to help reduce spam. search "Postfix zen.spamhaus.org" in Google will show you sample setting.
