I am running Oracle Collaboration Suite 18.104.22.168.0 on RHEL 2.1. My domain *@abc.com has been receiving lots of spam. The messages are usually from yahoo with randomly generated username's like email@example.com or firstname.lastname@example.org, etc. The IP's behind all of them are different. The problem is that the Oracle Email component doesn't check and filter emails intelligently. Either it will block yahoo or we have to enter each and every IP address from which we are being spammed manually. Is there a possible solution to stopping these mails from reaching clients at @abc.com? Can spamassassin be integrated into OCS??
