Hello. I use BSD and Solaris on my networks. I would like to see a port of Zimbra to Solaris SPARC/x86 (i386 centric on the x86 port for compatibility), and FreeBSD 5.x/6.x on i386 arch. I would like to add that both platforms have JDK and JRE supported now. Only about a month ago, Sun made an agreement with the FreeBSD Foundation so that vendors could distribute precompiled binaries of both the runtime and development kit with the same conditions and compatibility that enterprises desire.

OpenLDAP, Postfix, MySQL, Perl, Bash, Cyrus, Sasl, GCC are available on both platforms.
Thank you for considering this, I'm getting tired of having to run RHEL and other Linuxisms on machines that were bought to run FreeBSD here. Zimbra is an awesome suite, and Solaris is an enterprise OS. FreeBSD is quite popular in the datacenter, especially on multi-core and multi-cpu racks, so let's pump out a beta for us to test. I'll personally test them out if you need it done.
