How to setup email forwarding with own domain on Amazon EC2?

Currently there is no incoming email (POP, IMAP, etc) managed service from AWS, so you'd need to set up your own mail receiving and forwarding.

Using Postfix as a mail server, setup would look like this: http://www.cyberciti.biz/faq/linux-unix-bsd-postfix-forward-email-to-another-account/

If forwarding is all you need, you could set up a email service outside AWS (Google Apps?) and redirect using GMail rules, for example.

UPDATE: Amazon Web Services has announced WorkMail as a email and calendaring service. http://aws.amazon.com/workmail/

UPDATE: Amazon SES now supports inbound mail

Use a mail forwarding service. Eg. improvmx.com

It allows you to forward emails directed at your domain to any email address of your choice. All you have to do is add an MX record for your domain to point to improvmx.

And its free.
