Thanks for the suggestions. I have to admit that I haven't looked at the iMail logs regarding this specific issue; I have never been able to find anything there that indicated how many connections were being used. But NetStat shows hundreds of connections, and telnet indicates 40 to 50 connections being processed at times. And connections appear to get slow when this number gets over 20-25, though I don't have any empirical data. We do have a Barracuda in front of the iMail server which performs essentially the same functions at an IMGate box would AFAIK. But we do have some client MX Records that point directly to the iMail server. To this point at least we have not forced all clients to use the Barracuda filtering.
