So I just set up a new EC2 instance on AWS (Ubuntu AMI) for a WordPress server. I'm pretty good with setting up the LAMP stack stuff but I have no idea how to get the server to allow email to go out. This box will never be used for receiving email, just sending. So is there something special I need to do for this. I installed mailuitls but that's as far as I got and I'm pretty sure I screwed that up.
