1 MTA, ie. qmail, is hardly "lots of MTAs". On the contrary, most modern 
SMTP servers support SMTP AUTH. The list includes sendmail, exim, 
courier and postfix. qmail was written in 1996. For its day, it was very 
advanced. But it has failed to adapt, and it supports many useful 
features only with patching, which is a bit of a black art with all the 
different patches floating around. You should really consider moving 
away from qmail.
