He's suggesting that mail sent direct-to-mx from arbitrary university IP
addresses is unlikely to be trustworthy. I presume that when the OP
said  our "entire network is on the blacklist", he meant that the
university has put everything but it's own mailservers, into the Policy
Blocklist, and that he is trying to run an unofficial mailserver.

As regards the original question, unless I missed an RFC or Microsoft
implemented something proprietary, you can't send outgoing mail through
IMAP. The normal solution to the problem is to configure sendmail to
relay through a submission server.
