[EXIM] Version of Solaris

We're about to replace our current PP based mail hubs with exim. As we're
starting on a new server it seems sensible to use Solaris 7. Does anyone
have any advice or opinious on whether this is sensible (or should we stick
with 2.6?) and if so which version would be better (32 or 64 bit?).
