A MTA will expect input in a certain form, will check and munge it before queueing. I think you should first get a grip on how mail transfer in general works. AFAIK the basic principle for both in/outbound would be to have a (proxying) service on some port which would handover to the MTA/MDA. Take a look at for instance adding Spamassassin to a MDA.
