I agree, if you have no need for the Groupware features, there is no
reason to purchase or build a product that does have those features.

Would you kindly let me know which Internet Protocols and features you are
speaking of, and please list the version or versions of Exchange that go
with those limitations.

Good point, you preferred the ability to 'control your destiny' rather than
have someone else do so, I am the same, thus wy I use exim as my MTA.

No, you do not have to be large, just knowledgable of the products that you
will be using.

Most if any do not have SQL lookup types, but there is a very wide range of
products that support LDAP for address-books and some that do so even for
user prefrences. Only problem with LDAP address-books is that no one seems
to agree completely on what the LDAP attributes should be, although things
have been getting 'corrected' in that respect.

All Exchange user information is available over LDAP, are you suggesting
that LDAP is a pseudo-database?

They let people build thier own with or without Exchange, any Exchange
installation and any MS Active Directory installation support LDAP. LDAP
has become the 'way to find things' when it comes to that sort of Internet
data.
