Oh boy, an email question!

Time to dust off my memories...

How sendmail-centric of you. With Postfix (which I'd recommend for this) your 
term is relayhost.

Right. A relatively dumb "forward and forget" system at the originating system 
makes sense; the inbound IP restrictions (add each one in my_networks), the 
rules for Fred being a princess (transport_maps will save you here provided 
your routing table is correct), message_size_limit will help-- but be aware 
that you probably want to go 33% high on this number; MIME encoding adds some 
overhead. 

If Fred needs to rewrite the envelope, header_checks can do this.

Lastly, this seems fairly complex. I think you might be better off pushing back 
against some of these requirements; it's a bit arcane!
