Configuring client Exchange mail scanner

We recently got the SBS edition of Avast running on our intranet and I’ve run into a bit of a snag…

The Avast! mail monitor reports suspicious emails but we’d like the ability to customize it. We have several clients who frequently send emails with no subject line, but we would like to be able to add their email/domain name to a safe list to prevent the nag from popping up each time we get an email from them.

I was poking around the ADNM Console but didn’t see anything relating to managing the actual behaviour of the client processes… Is this possible with Avast?

Thanks for any tips!

Does the Exchange plugin has Heuristic tab of settings like in the PC version?
Unmark the ‘Subject check’ option.

Won’t this able to be customized by the Computer Catalog settings?
I’m not sure as I’m a PC user and not the Server version user :-[
