Bzzzzzt! Please don't erroneously compare CURRENT sendmail with CURRENT
(that's 1.0.3) Qmail. Qmail has a single queue directory, sendmail-8.11
ALLOWS you to have multiple.

I'm afraid sendmail is catching up... :-)

People for years have hacked sendmail to do multiple queues for large sites
- just like Qmail has been hacked... But Sendmail officially supports it,
Qmail doesn't.
