I suppose I ought to clarify the VopMail package a bit. It DOES have anti-bulk features that are administratively adjustable. I don't want anyone to get the impression that Vircom has mis-represented their product. We stepped into the situation with both eyes wide open, and have been otherwise pleased with the reduction in the amount of unsolicited material it stops from getting to our users mail accounts.
Perhaps the piece of information I'm seeking is the number of invalid addresses that SIMS must receive from a particular IP/server, before adding that host to the temporary ban/blacklist pertaining to "suspected address harvesting" I should be able to set the Vircom VopMail settings to a number lower than that, and solve the issue--"should" being the operative word.
