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! Regards, Kaya
