New Code!
Postoffice has been pushed up to version 1.1.7a, which cleans up some annoying bugs, fixes a denial of service feature when disks get full and you're running with antivirus code turned on, and adds a couple of configuration features to resupport running on systems that don't have a properly functional flock() system call. Postoffice is mature enough now so there aren't that many new features I can think of adding to it, so this is just another bugfix release to push the code towards a happy reliable state.
But if there are any features people want, I'd be happy to listen (like, oh, disk space checking that works. But I've already fixed that...).
