Frustration and confusion over setting up a Postfix mail server on my

[dag10]

To start off, It's worth mentioning that I'm still very confused about how the whole mail server thing works, and what software handles what job. From my understanding POP3 and IMAP are protocols to pull email from a mail server, and SMTP is used to push email to a server. There are many programs that I've seen involved with creating a mail server, but I'm trying to use just Postfix. Postfix can send and receive email right?

My server runs in my basement and runs Ubuntu Server 10.10. It uses Cherokee as its web server, and it runs several other servers as well (SSH, FTP, Git, etc). My goal is to set up a mail server so that websites I run such as a Redmine or a web forum can send emails to people (e.g. an activation email for a user registering on a forum).

Anyway, I set up postfix, and now my server can receive email. I've been able to send an email from my Gmail address to drew@mydomain (my server), and it works. However, if I try to send email from drew@mydomain to my Gmail, it never goes through. I don't care about receiving email, as my only goal is to be able to send it.

I can post any configuration files you want to see. Any help is appreciated!
