"yet another smtp..." sounds like you think you have too many already, but 
you only have, qmail for an MTA, and Vexira for SMTP AV.  What's wrong with 
a third small application for SMTP delivery?  It could even run on the same 
machine.  I run Windows OS's so I use the built in MS SMTP service that come 
with the OS as the delivery mechanism.  Low overhead, stable, and gets the 
job done.

Why not use DNS for delivery in Vexira instead of setting a "destination 
smtp server"?  Is that not possible in Vexira?  Since it runs on a different 
machine than your mail server qmail, you could point all the domains you 
manage to your qmail's local IP using local DNS settings to manage incoming 
external email and it would deliver non-local email via DNS to the Internet 
for outgoing email.

This will work to skip Vexira for local-local mail, but I use ASSP to block 
attachments coming from the Internet that I do not want to block for 
local-local mail so it still would not work for me.  Plus, we do a lot of 
internal mail, sometimes with largish attachments, so I don't want my server 
wasting time passing all that traffic through ASSP too.

The most efficient plan is to restrict internal mail to just the client and 
the MTA and have multiple layers of protection for email coming in from the 
Internet.
