My employer is considering replacing the proprietary local area
network e-mail package we use.  This posting is a request for information
about what alternatives might be available.

We have about 500 '286 and '386 machines running one version or another
of System V *NIX, networked via Ethernet running a networking package
called "Fusion" (tm).  We use Fusion's XNS product.  In addition, we
have 4 VAXen (one in a separate city, linked via 56kb circuits), running
BSD; Fusion also runs on them.  Finally, we have a few Suns that do use
TCP/IP and a handful of protocol convertors which connect the Suns to
the rest of the LAN.

The mailer we use is a non-RFC-822-standard package and is, as noted, a
proprietary one which replaced /bin/mail on the workstations and BSD Mail
on the VAXen.  We are not now connected to the Internet.

What mail delivery agent(s) might work in such an environment?  (We do, of
course, have BSD sendmail, although the current mailer does not use it.)
What user agents will run on the '286/'386 workstations?  How would routing
occur?  Are the System V versions of sendmail reliable?

At this point, we do NOT expect to be able to move from use of XNS to TCP/IP,
We probably won't be able to upgrade the '286 *NIX, which is 
System V.2.

Naturally, we hope to be able to run something in this environment that
won't require replacement of our existing network software.  And, we'd
prefer to use something like 'elm' which is widely available at low (i.e.,
no) cost.

Thanks in advance.  Please reply via e-mail and I will summarize.
