I'm new to Exchange & AntiSpam/AntiVirus. We have implemented an IronPort C150 AntiSpam appliance. I have it set so that Spam gets deleted, but suspected spam gets delivered and my users can decide if they need it or not. Well, we're getting a lot of "medicine" emails that aren't getting deleted. I know how to blacklist by sender, but was wondering if I can blacklist by subject keyword. I would like to delete any emails that come in with Viagra or Cialis in the subject line. What's the best way to do this?
