Repeat after me: “You don’t have to run Microsoft Exchange Server”.
Don’t get me wrong, MS Exchange is a great product IF YOU TAKE ADVANTAGE OF ITS ADVANCED FEATURES.Â However, it isn’t cheap to own or maintain and contains a lot of functionality that often isn’t used.
In fact, I believe that 70-80% of companies that are running MS Exchange could probably migrate to an internet standards based mail server running on Linux or FreeBSD without giving up much in the way of functionality that they actually use.
I’ve recently setup corporate mail servers on both Ubuntu Linux and FreeBSD that incorporate Postfix, ClamAV (anti-virus), SpamAssassin (anti-spam), Dovecot (POP3 & IMAP), and Squirrelmail (webmail interface). These mail systems are secure, inexpensive, easy to administer, and can be used with MS Outlook, Mozilla Thunderbird, Evolution, and virtually any other mail client you can think of.
Give me a call if your company needs a new mail server!
