[comp.protocols.tcp-ip] Mail servers

lwilson@umabco.UUCP (Lowell G. Wilson) (07/15/89)

I'm not altogether certain I am posting this to the right newsgroup, so
please bear with me. 

Our shop is in the process of stringing fiber across the campus to
create a campus LAN.  Currently we have lots of users connected to
Novell, 3-Com and Starlan networks.  Additionally, we have a PACX data
switch that grants access to a UNIX-based conferencing system and an IBM
mainframe.  All of this stuff will eventually be hooked up to the campus
LAN which will have a TCP/IP router hanging off of it.  This means that
several independant electronic mail systems might just be able to talk
to one another? I was wondering if anyone who has done this sort of
thing could send me some ideas.  Right now we are running Profs on the
mainframe, plain vanilla UNIX mail on the UNIX box, and 3-Com, StarLAN
and Novell mail on the file servers. 

I THINK what I need to find out is if there is any way to get all these
systems to talk SMTP and, if there is, if there is any way to get them
to forward mail not intended for users of their systems to some default
SMTP mail server.  Our mainframe is rather underutilized, so if there is
any way that machine could be used as an SMTP mail server, that would be
great.  

Any help would be greatly appreciated.  We're a ways away from getting
the fiber strung so I'm just trying to get a handle on the problems
we're going to run into and mail seemed as good a place to start as any!
If I have left out any needed details (doubtless I have) I'll be happy
to fill in the blanks as best I can.  Thanks in advance for any
suggestions...
