Three points:

1)  I still think that ODMR should be done on the SMTP port, rather than
some other port, since a new port requires that the mail server on the
customer side connect to 25 to send mail, then to xxx to dequeue mail.  It
might be that for some mail server implementations it's easier to do this on
a port other than 25, but that should not drive the protocol specification.
This functionality belongs as an extension to SMTP rather than as a separate
service.

2) I don't think there should be domain arguments on the ATRN command, as it
places an unnecessary burden on the administrator of the customer side to
enter the proper domains.  Much simpler is for the server on the provider
side to associate the appropriate domains with given authorization IDs
(which needs to happen anyway) and have the customer side just issue an ATRN
devoid of parameters.  Much less to go wrong, fewer customer service calls
for the provider.

3) I don't see the lack of queued mail as an "error" condition worthy of a
450 response.  Sad, perhaps :-(, but not an error.  I'd suggest just issuing
a 250 response if the customer server has authenticated properly, followed
by the (perhaps nonexistent) messages, followed by QUIT.
