Does anyone have some tips on blocking spam from reaching the mail queue? The server is running WHM 10.8.0 cPanel 10.8.2-R119
RedHat 9 i686 - WHM X v3.1.0 and the mail software is Exim. I have SpamAssassin running as well, but it seems that the volume of spam alone is taking up too many resources for the server to keep up with.
I've check the logs and it's not coming from a single IP or cluster of Ip's, so blocking IP addresses wouldn't work.
Doees anyone konw of any good techniques or software (anything) for dealing with spam?
Thanks for any help!
