You probably do *NOT* want to put the hacked version into the SMTP dialog.
What is happening is that the ARPA host is also adding its name to the path,
so you end up with two copies.  If you just put "person@local" into the
dialog, MIT-MC.ARPA should create one of the two following forms:

     person%local@MIT-MC.ARPA
     @MIT-MC.ARPA:person@local

which is (I believe) the right thing to do.  Note also that many people use
the buzzword 'Out-Of-Band' to refer to the data in the SMTP dialog, since it
is not part of the message text (In-Band) information.

As to the headers.  If MIT-MC is "munging" headers, you do not want to put
the hack there.  This seems to be the case from the information you gave.

So you probably do not want to put the hack in at all.  If software everywhere
is working correctly, you do not need to.  Don't treat this as gospel from on
high though - experiment and use whatever seems to work correctly in all cases.
