Yes.

True, I will dump out the mailboxes and see if it truly was incomplete. > Those hangs are a little bit annoying to debug, and the whole code has > been rewritten for v2.2 already in a way that should make the hangs > pretty much impossible. Annoyingly v2.2 isn't ready yet.. I have found a manual work around. I use rsync to get the files over to the backup machines, then I let the backup script keep things up to date. It is not the best way to go, but at least I have backups. I suppose I can check the log and continue to rsync things over until 2.2 comes out. ...Jeff
