It's late, and I've enjoyed entirely too much wine, and I've not
reviewed this thread particularly much,, but still.... If one
perceives this as problem, then why not do some simple AV-scanning at
the MTA level first? milter-clamav or some such comes to mind. Then
let the rest (MS/SA/other AVs) kick in on everything that survives the
initial check.
Anyway, just a thought. This pops up from time to time, and the longer
I've used MS, the less... necessary... the "changeability" of order
seems to me.

Best kind:-).
I'm rather the other way around... Started as a "trained" programmer
(in ancient history:-), but slowly diffundated(sp?) over to more
traditional sysadm. Taught myself perl though.... Can't really say the
traditional training in imperative and functional prog langs really
helped much:-):-) Guess I'm just trying to say "Thanks for a great
product", in a rather roundabout and... mellow way:-)
