    We run a 35,000 mailbox system with no problems on Solaris.  We did 
a few years back have a bad time with using Berkeley DB and cyrus and 
switching to skiplist fixed that.  I believe that problem has been 
solved though.  I would recommend using multiple spools however, having 
one big one would scare me to death.
