I am using sendmail server on RHEL5 and facing spam issues. My IP is blocked by CBL - Spamhaus.
Please suggest how can i check first of all that spams are not being generated from my sendmail server and secondly how can i configure spam filters not to alllow spam from and to this machine?
Please mention some links that can help me to implement spam filters on sendmail.
I am desperately waiting for this question's reply.
