I would second second the thoughts that Mike had about LDAP. I tried
to use OpenLDAP as a "person database" about a year ago for exactly
the type of setup you are talking about -- it was a good way to waste
a week. I ended up going with a mysql backend instead of LDAP (and I
seem to recall there were some squirrelmail modules which allowed you
to create contact lists in mysql also...).
The good news/bad news with Postfix and a mysql (or any db, including
LDAP) backend is that you can find notes and howtos from many people
on the web and all of them work but each one does it slightly
different. So until you finally put it all together once and it
actually works you can get pretty confused trying to troubleshoot why
your particular installation does not work..and why did one person do
it one way and another person did it another way. The reason why is
that Postfix makes everything configurable. After I finally got mine
working, I had an A-ha moment and it all made sense, but until that
moment I was just trying to blindly follow someone else's instructions
(which might be only 80% complete).
At least with a Mysql backend there are many people that have done it
and you can figure out from the many different tutorials how to
actually make it work. With a LDAP backend there are very few
people/notes about how to make it work. LDAP seems simple, but it is
not something to start with lightly. You quickly run into things
like: how do you edit the LDAP database, how do you modify the schema,
etc. Things may have changed in the last year...
I have used squirrelmail with a postfix/mysql setup and it works
pretty good; however, I have not hit it with a substantial load so I
can't speak to its performance under fire.
Hope this helps,
