[Blind-sysadmins] Inbound and outbound mail not working properly with Postfix.

Good morning, I@m looking for a fresh perspective on a problem that I've had with my main web server. After rebuilding it, inbound and outbound mail aren'tw orking correctly. I know this is a mistake I have made with the configuration but I'm at a loss as to what's gone wrong. If someone would be so kind as to give me ten or twenty minutes to take a look I'd particularly appreciate it. Thanks Darragh
