yes, its quite true. i am sure qmail has patches to do both of the works.
but, it is also the problem itself.
qmail has too much patches, after patching so many times it becomes unstable.
postfix is not good at performance comparing to qmail (i mean slightly slower), but it can do the same things in the painless way.
ps: and i dont ever know any patch that qmail does all deliveries at one smtp transaction.
