However, you said it was running under Postfix. I have no idea how well
Postfix manages local delivery concurrency. With qmail, it's trivial.
Perhaps your proprietary MDA would work perfectly well with qmail with a
local concurrency of 10, or 20, or 5, or whatever.

Delivery to local users (and virtual users, etc) happens through qmail's
included MDA, "qmail-local". qmail-local can be configured through many
different means to use other arbitrary MDAs as well (maildrop, procmail,
etc), but it's built-in support includes Maildir delivery, mbox-rd
delivery, and message forwarding.
