The HP product OpenMail lives on as Scalix. It's not the best license but it has a goood community. They were purchased in the fall of 2007 by Xandros which has a "special relationship" with Microsoft. It's a bit of a worry but so far so good.

Scalix can push email to Blackberry's and the Blackberry desktop sync program works well with the Scalix - Outlook combination. Scalix promises better integration "shortly".

While it installs with sendmail, it does allow use of postfix, amavis, spamassasin, and clam. For the most part "plays well with others." Like Zimbra it does tend to take over but not NEARLY to the same extent. For example we have successfully integrated Samba on the same server with good results. YMMV
