Mail server suggestions?

[Phillip Rzewski]

     I have been looking to open a mail server for quite some time and as much
as I have tried to do it the hard way I have come up empty thus far. First I
attempted to read some manuals that might give me the tools I need to write my
own, but I lack the time and raw Unix experience with mail and the like to make
it all come together. I got someone else's homemade server software, but it
was sparsely documented and he admitted right out that it was in sore need of
a rewrite. I even bought more manuals to read to try and figure out what he did
so I could build on it. But even with all these attempts I am still in great
danger of coming up empty by the date that I need this server to be working
by.
     So now I look to comp.unix.questions to see if anyone would happen to 
know of a decent mail server program that has good documentation, is flexible,
and can be friendly. I am working on a series of AT&T 3B2 machines, each
running SysVR2 or R3. We have sh, ksh, csh, and bash available on all of them.

     Please respond by mail if at all possible. I apologize if I posted this
to the wrong place, but having read the little "intro guide" I saw nothing
that indicated that this was a bad question to ask around here. Thanks in
advance.
