I have to agree wholeheartedly with the recommendation for a Solaris port.
With a heavy background in Solaris sysadmin in an enterprise-class Solaris/SPARC shop, I must say that Zimbra would be making a wise business decision in porting to Solaris Sparc/X86. Folks in 'corporate' would *love* to have an alternative to Exchange and reduce overall costs. But any collaboration suite solution must be supportable on equipment that can be truly recognized as enterprise-class and that leverages the experience of existing IT staff. Zimbra should be able to make money from that category of shop by the wheelbarrow-load.
