Well, my current MDA is an intermediate (read that as "bodged")
version.  This release uses procmail and a custom recipe to
actually stuff the messages into the appropriate mailbox.  That
being said, I do, however, plan to add the actual mailbox delivery
stuff to the MDA.  I may do it over the holidays (but don't count
on it--I'm gonna be busy).

Keep in mind this version of the MDA does the following functions:

	forwarding (up to 20 forwarding addresses, could be more)
	autoresponder
	mailbox delivery (soon)
	mailing list (Majordomo-style)

Just what actions are taken regarding a message are driven by
attributes contained in the virtual user's LDAP entry.  It runs
setuid() and setgid() to mail, but is quite secure (there are no
possible buffer overruns or other little gotchas--I'm paranoid).  It
was designed to run with sendmail, but should have no problems running
with other MTAs--provided they use external MDAs.

As to mailbox format (and assuming my people will let this out under
GPL), which mailbox formats would you like to see supported?  "mbox"
is a given.
