Thats a new one on me...
The answer is not at present, and having had a quick look I don't think
it needs to since this can be done with external tools....

On the server end, mail is delivered into some form of per user/domain
hold spool - ie something like a maildir per user/domain. The ODMR
server listens on port 366, takes the auth and pushes mail back by SMTP
on the existing connection - thats a very simple process to code,
especially if you make exim (or your MTA) save the mail into this spool
in BSMTP format.

On the client end you have a separate (from exim) process fire up,
contact the mail server and auth, it then starts an exim -bs process
and it just works.

So thats 2 programs that need writing, both of which are a few 10s of
lines of perl or a couple of hundred in C.

The most complex part is the auth handling in the server end.
