Hello, I'm trying to find a guide that will help me setup an MTA on EC2. The users using email/having an inbox will be users who sign up on the application (Flex on Rails), so its not linux system users. I'm using Cent OS 5.2, MySQL and for DNS stuff I'm using PowerAdmin (if that's relevant). I've found a guide on here for 5.1 http://www.howtoforge.com/exim-mysql-cyrus-imapd-horde-centos5.1 and another one http://www.howtoforge.com/virtual-users-and-domains-postfix-courier-mysql-centos5.1 but I don't really understand what's the difference between the two setups and I'm not sure if everything will work out the same way with 5.2. Any hints, tips, guides or anything would be really appreciated. Thank you! Simon
