I have a qmail server living on an Amazon Ec2 instance, it's primary purpose is to receive a large amount of incoming mail, which it does fine. It also wants to forward a very small portion of the mail that it gets, but one of the things about ec2 is since the machines use dynamic IPs, you cannot send outgoing mail on ec2 without it being blocked by most recipients. The solution for this is to not use ec2 for outgoing mail, or use a relay. Option 1 isn't available to me so I'm looking to have my qmail server send outgoing mail to a relay. I have little idea how to do this. Can someone point me towards how to set qmail to use an outgoing relay server?
