Jordan Bortz asks for a:

	good mail system (for SYS 5.3 (Interactive Systems 386), actually)  
	that will do path aliasing -- eg expand

	   USER@HOST		to 		sys!sys!sys!host!user

        Does anyone know of such a beast, and how I could get it?

There are a couple of mail systems (actually I imagine you're talking
about a mail User Agent, not the same beast at all) that know about
the pathalias database.  Of these I would suggest that you look
into acquiring The Elm Mail System, which does at-that-point alias
and host address expansion (e.g. you can type "alias" and have it
replaced immediately with the aliased address if it's an alias, or
can type in "user@host" and have it replaced immediately with an
appropriate route (e.g. "user%host@other-host"), AND you can have
address like "user@host.domain" expanded based purely on the 
particular domain specified (for example, on my workstation I have a
rule that says "if the domain specified is ".bitnet" then rewrite it
to go through the WISCVM gateway, so my saying "elm JOE@NYUVM.BITNET"
is rewritten as "To: JOE%NYUVM.BITNET@WISCVM.WISC.EDU").  These are all
supported in parallel and can be turned on or off independently).

The Elm System is available through the mod.sources (er, comp.sources.unix)
archives near you with patches and other discussion to be found in the
newsgroup "comp.mail.elm".  It really is a pretty nifty mail user agent,
if I say so myself...
