I would like postfix to send mail being delivered to a specific

setting up mimedefang are just to set it up as a general milter.
Milters ARE general intrinsically. MIMEDefang is only usable as a
milter
Or do I need to configure mime defang itself to only process the mail
to that user?
That.
It's VERY easy to do. Your mimedefang-filter will have a subroutine for
each stage of the transaction. For each one that you enable (controlled
by options to the mimedefang daemon) after filter_sender() you have
either a single recipient (in filter_recipient()) or an array of all
extant recipients (in filter_{begin,end,multipart,wrapup}().) You can
put a check for the special user at the top of the subroutine and call
'return action_accept();' if it's not there.
Note that things can get messy when messages have multiple recipients.
Ways of dealing with that (basically: forcing one recipient per message)
are documented in the MIMEDefang docs.
Also, right now it is setup with
-s /var/spool/MIMEDefang/mimedefang-multiplexor.sock
Does it need to be a port instead?
No. RTFM. The MIMEDefang package includes 9 man pages.
(Most the stuff I can find is a about decade old and the rest is even
older, so I have little confidence)
Yes, it is stable software. While Dianne Skoll was the MIMEDefang BDFL,
she kept scope-creep under control and wrote good code, so there has not
been a lot of novelty for users of MIMEDefang. It mostly just works. It
is not dead, and a maintenance release will be coming soon with a
handful of fairly small fixes.
