Using cPanel as a spam filter for remote mail exchangers

[LostNerd]

I recently had a question, and I wasn't able to answer it! I need answers! :p

Do any of you know of any way to use cPanel as a sort of relay where it will run a spam scan and then pass it on to the remote mail exchanger? For example:

Spam Mail -> Recieved by cPanel/Spam Assassin -> Mark as spam if required -> Deliver to External Exchange Server

Any suggestions are appreciated.

Hello,

There's no native support for this, but you may find the following threads helpful:

Thank you.

Thanks for the suggestions.

Unfortunately, those suggestions don't appear to work for me. I need this to be on an account basis due to only some accounts requiring this set up.

You may want to try the Exim users mailing list to see if anyone else has configured Exim this way:

Hi LordNerd and all,

Did anyone ever figure out how to clean mail on the Cpanel server via Spamassassin and then relay mail onto the customer's Exchange server?

As of yet, unfortunately not. I've resorted to building a standalone VM running Baruwa. A free spam filtering/mail relay server. This filters the emails and then delivers or quarantines on a per domain name basis where you can define the endpoint server per domain.

Thanks for your reply.

Do you have a simple how-to for quickly setting up a Baruwa server and integrating for a specific domain, i.e how and where do you deliver or quarantine on a per domain name basis where you can define the endpoint server per domain?
