Because sendmail is rapidly fading into history?

There are numerous IMAP servers that support maildir, and scripts to
import MBOX files - that is how I would approach it.  [But then I
wouldn't use Maildir; I mean, really, who cares what format your
messages are in - use IMAP and network access your message store.  Cyrus
IMAPd will index and filter all your messages for you].
