I would appreciate it if you could send it to me - thanks a lot.

well, the 300K messages folder does not contain that many messages any more
(unfortunately). I just synched once to make a backup of my mail and then
deleted it. I have about 5K messages in there now, and with my +/- 200 junk
messages per day, it'll be quite big quite soon.

Anyways, I'll try it out and then post the results.

Thanks,
Bernhard
