Thanks for that Jan-Jaap. I haven't re-read the documentation since the last few updates so I'll have a go. The current version can take a little while to process incoming email even on an Iyonix if you set the hashtable size too big. Having the machine freezing for a few seconds every 10 minutes is a pain. (And before you all flame me, I know this is OT - sorry).
