Hmmm....  I've had problems posting messages with attachments too.  If I
just insert the file in the message all is OK, but using a proper MIME
attachment causes it to go into a black hole (which may or may not have
been the manual approval process).

The delay is not so small sometimes, depending on the queueing policy of
the sending MTA.

I would recommend turning off greylisting, as an experiment, to see what
happens.  I've found it to be entirely counter-productive.  It hasn't
been useful for literally years now -- the spammers have long ago adapted.
