Yeah the disk is relatively empty:

# df -h
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/da0s1a    7.7G    5.2G    1.9G    74%    /
devfs          1.0K    1.0K      0B   100%    /dev
ZPOOL_1        9.8G    1.1G    8.7G    11%    /mail


The PST's seem to be stored on local hard disk too.


It seems that there was an issue with Send/Recieve settings that my
manager has made me aware of, basically turn off the Auto Send/Recieve
and it seems to marginally improve performance??


Well thanks to all and I guess we'll keep testing ;-)


Dovecot rocks, it's just a pitty that there is so much poorly
programmed corporate software out there!
