We are having a problem where our current filter, Xwall is not catching a significant # of pornographic emails to a few users. I am looking to see if this is a common problem with xwall, and if users have advice on a better filter or configuration. I've heard some about Vamsoft's Open Relay Filter and a few others. And I'm wanting to get opinions. Also if people are having good success with Xwall, maybe a link to tips for configuring xwall to better catch porn. We haven't been having much problem with spam, but porn seems to be especially tricky and keyword blocking is not enough. We have alot of very important emails that are sent daily and cannot afford to have them blocked, so its difficult to tighten down security.
