Essentially, I need a modern mail server to host about 100-150

Well, to be clear, with a OS X or *nix solution, each of these
things is usually a separate program. For example, I use postfix
for handling incoming and outgoing mail; uw-imap for some IMAP
access and Courier for the rest; anti-Spam comes from SpamAssassin,
kept up to date; web-mail is provided by SquirrelMail and Roundcube;
SMTP Auth is provided as a 'back end' service via pop-before-smtp;
multiple domains are handled by postfixadmin; mailing lists by
mailman, and forwarding is also provided by postfixadmin.
I don't provide a vacation service because they are nearly always abused.
The major reasons for providing 'vacation' services are:
1. You want local correspondents to have that sort of notice, i.e. in
a business environment.
2. You want to avoid having users set up their own (usually very
broken) autoresponders instead.
* Integration with single-sign-on solutions--CGate works with
Kerberos (which also gives me Active Directory as option) as well
as external helper scripts supporting LDAP, PAM, and RADIUS.
Does it makes any sort of sense to have a single sign-on for a IMAP
connection and a webmail conenction? What do you mean by single
sign-on?
It makes a lot of sense in a business environment where mail is just
part of the picture.
And in fact the capability to work with a rich collection of
authentication mechanisms has become pretty much the norm for mail
tools in the free software world. The difference between CGP and
Postfix+Dovecot for authentication is not so much what is possible
but rather how deep an understanding of the SASL/GSSAPI/Kerberos/AD
technology tangle one has to have to make it work.
* Palm Treo support
If the treo supports IMAP then I support the Treo.
Yeah, that's pretty much an unanswerable. Different versions of the
Treo ship with different OS's and mail clients (for example, the
Verizon mail client for PalmOS is a featureless piece of garbage, but
the ChatterMail client recently acquired by Palm is very slick... ) I
cannot speak to the Windows Mobile versions, but anyone with a PalmOS
Treo either already has or easily can get a mail client that will do
POP3 and IMAP. Quality and user experience varies a great deal, but
that's mostly a client-side problem.
* simplicity and ease of configuring accounts and performing
maintenance tasks; I really need to be able to delegate functions
to staff who may be less familiar with the system than I will be,
not to mention times when I'm away.
Well, as far as maintenance there is none. Each domain is
administered vi postfixadmin, where they can add or remove accounts
or aliases at will. I don't do any of that, generally.
You're talking about an ISP environment, I get the sense that Elliot
is talking about a business environment. Very different cases.
Can anyone speak to the capabilities of the alternatives in these
areas? The last three are really essential. Also, the ability of
CGate to function in place of an Exchange server could be a
considerable benefit in the next year or so. So if that capability
is available with any of the alternatives, it would good to know.
I don't think there are any alternatives to CGate that are nearly as
easy to use and setup. You will be spending a lot more time keeping
software up to date, patching security holes, and probably a good
couple of months in run-up time just getting it all working the
first time.
If you want CGate Pro, then pay for CGate Pro.
Absolutely. There is no better choice for a mail system that just
works. MacOS X Server may come close, but it does not really beat CGP
and some people don't like being tied so tightly to Apple.
