Alright, I've followed this howto through however in the mail.log I keep getting the following error popping up whenever I try to send anything, and obviously the mail never sees the light of day again...
For the life of me I can't figure out why it's trying to run /usr/lib/postfix/2, there's a number of other executables in there but no 2, and search as I may I can't even find references to anything like this. Any help you could offer would be greatly appreciated.
