Qmail by design delivers separate copies of every message even when the
destination host is the same while all other major MTA's group them with
multiple addresses in the SMTP envelope. This is very inefficient, especially
when your typical communication is to business groups at different locations
connected by slow and expensive private lines or even if you have a slow
internet connection. Also, when you add spam and virus scanning, that
must be repeated for each recipient as well, plus you are imposing this load
on everyone else compared to grouped messages. Sendmail allows much
easier control over allowed traffic with database lookups in several phases
and the new 'milter' interface allows separate programs like MimeDefang
to control processing with spam/virus scanning done concurrently with the
SMTP reception. With qmail you have to accept the message before you
can look at the content, then if you decide to reject you are obligated to
construct and send a bounce copy.
If you look at the qmail license, you'll see why it hasn't been improved...
