+1 to what Laura says. I run a couple of EC2-hosted mail servers .... but I smarthost their mail out through another server, because, if you can get Amazon to unblock port 25 for you, people are still probably going to reject your mail far and wide. The EC2 IP ranges are likely to be treated unkindly both based on the presumption that it's not really a mail hosting neighborhood PLUS anybody who has run a spamtrap network and watched for connections coming from there tends to figure out quick that it's mostly weird stuff like random SMTP tickling for unclear reasons and security testing/threat research. I would not and do not want my legit mail to be part of that neighborhood.
Either don't run this in EC2, use SES to handle outbound, or do it my convoluted way and smarthost the mail out through a whole other dedicated server at a completely unrelated ISP that has a good reputation. I'm not even sure I'd recommend it, but I've been doing it for years and years, so it's really more a question of inertia at this point. I might have had this server as a mail server going back to before Amazon SES launched.
