Please don't top-post; trim the quotes down to the relevant parts and address issues below the quotes. Okay, it was ambiguous what you meant when you said "We have an application which needs a mail relay to send emails out" - most would assume the application is running on the mail server. The short answer is no, SASL is the only authentication mechanism available to Postfix. SASL is a protocol, not a backend, which means it's flexible enough to fulfil pretty much any perceivable requirements. http://www.postfix.org/SASL_README.html You'll want to start here. SASL isn't particularly hard to setup, but it'll take some work to fully understand. Understanding how it works is important for ensuring it's providing the security you expect. Postfix has support for two SASL providers, cyrus and dovecot. Cyrus and Dovecot are both IMAP servers, but they happen to also provide SASL backends. If you're already using one of these IMAP servers then there's less work to do. If you haven't setup either before, Dovecot is usually recommended as it's a bit simpler.
RE: Postfix Relay help
This is because the application owners want a setup where they want to relay mails out ,only through an authenticated mail server (like postfix).
