Thanks Sam... Now I understand why it's doing what it's doing. But this gives me another problem.... - How to determine that a message is spam and therefore decide to not throw it at Courier. I've been relying on courier's spam spotting ability (in this case typical senders in the BOFH file) to tell fetchmail to flush the email.... If courier was being contacted by an off-site upstream smtp mail host then delays would be a good tactic, but in my case, I've got a pop3 box at the upstream host filling up with junk and no control over that. I guess I have two choices.... 1. Find the delay and 'disable' it (any pointers or hints Sam?) 2. Find something to filter my email directly on my ISP, before fetchmail gets to it 3. Disable BOFH (or delete the entries currently on there) and use maildrop to match addresses and filter to a non-existant mail box (which would mean allowing spam to progress further... ie all the way into courier now just stopped at fetchmail. I realise that (2) is OT but for both I'd appreciate any hints from the list on this - there must be other pop3->fetchmail->courier users out there!
