I guess i'm at a loss here. Exactly how would trying each MX record in 
turn prevent your filtering techniques from processing reverse lookups, 
or  dynamic ip's.
but the guy is correct. qmail is owned by one person, and is not likely 
to change.  The followers of qmail,  I think, would have adopted such a 
MX strategy, if it was *exactly*  spec'd that way into one of their 
mandatory patches.
