Mail sending from EC2 using Postfix.
http://bipinkdas.blogspot.com/2008/05/one-of-main-problem-i-found-in-ec2-is.html
One of the main problem I found in the EC2 is to sending mail to outside world. Some mail servers like YAHOO and HOTMAIL will block all the orphan mails from EC2 as SPAM. So people cannot send mail like CustomerVerification,NewsLetter from EC2 comfortably.So I am hereby stating an alternate method which was experimented by Paul to get out of this problem. This is sending mails using POSTFIX
