On our Exchange Server, we're getting hammered with thousands of spam messages per day (as well as legitimate messages too). We've noticed that about 75% of the spam is directory harvesting and we have GFI MailEssentials installed. It's doing a fairly decent job. But with so much spam coming in, it's making our server difficult to deliver legitimate emails. Is there something we can do to prevent our Exchange Server's connection pool from being destroyed by these spam posts? Thanks so much
