procmail has supported maildir since hamm.

exim supports maildir since at least slink, possibly before.

sendmail does not support maildir, but it probably could if someone wrote
the rule to do it, or it's possible that a code patch could be (or has
been) written.

qmail created maildir.


The issue is that maildir will use one inode for each message.  It's a
terrible archival format and there's no real simple tool available today
for archiving messages in a maildir (though one should not be hard to
write..)

The only console MUA I know of which may not support maildir is elm-me+
and even it might.  Still, I believe it should be done by the individual
sysadmin---even though I have done it myself.  The admin is the best
person to decide if the changes made by switching to maildir are workable
or not.
