Postfix is a Mail Transfer Agent. It's secure, stable, actively developed and comparatively easy to deploy. It will send your email into the world, accept mail from the ever hostile Internet and hand incoming mail to your local storage solution. That's all any mail server can do. Your Postfix configuration will probably use a database - MySQL or whatever you're using for the back end of your site - to alias your "u...@site.example.com" addresses to the users' real email addresses. That's the extent of your Postfix deployment. You'll also use "always BCC" or a similar mechanism to copy all messages to an address where they'll be archived. For your site, you're looking for Java email libraries to send mail via the SMTP server (Postfix) and you have to make decisions about how to handle incoming mail to the archive. There are many ways to do that, including pulling mail off a POP or IMAP server or delivering to a command that parses the message and inserts the content into the data base. Chris Babcock
