While name servers are resource hogs, a well-tuned name server on a
sufficiently powerful machine speeds up everything. Please do not
attribute sendmail's apparant lack of performance on your badly configured
name server running on an underpowered system.

SMTP specs require a DNS lookup for every recipient, to find that
recipient's MX if it exists. If qmail does not do this it breaks SMTP
specs.
