I love working in linux, but I also have an enormous amount of Solaris clients that keep asking me what solution there is other than Exchange. Sun will tell you their collaboration suite is great - but let's face it, it's no Exchange. Zimbra is phenomenal and does everything our customers are asking for in a Solaris package that can and will eliminate Exchange. By porting to Solaris, you're going to get PAYING customers, not just the opensource community looking for a freebee collaboration suite that rocks. (no offense to anyone here - I want it for my personal linux server also). Porting it to Solaris will surely bring in revenue to help assist with other ports. Here's also a few other reasons:
1) Solaris x86 is becoming more widely used - Oracle, Symantec (Veritas) and numerous other major players are porting their software to Solaris 10 x86 because of the huge popularity that is gaining with their new AMD/Intel based servers.
2) Sun will offer any developer a free server if they port their software to Solaris (no, I do not work for Sun). I develop some code on the side and am registered with their developer site - which is why I got this link in a recent email:

3) Enterprise acceptance. Let's face it, very large corporations are running Solaris - a solution like this in their datacenter is priceless. As I mentioned above, I know many Global Enterprise customers (some with tens of thousands of seats) who have been waiting for years to move off of Exchange.
Just my .02 - Hope it helps!
Awesome product!
