my relay will be smtp.fastmail.com and it requires authentication and SSL, are there added settings in main.cf that will allow this?
What port is that delivering to -- that doesn't sound like port 25, which is the default that an MTA delivers to.
The postfix list may be a better place to ask these configuration questions. The general expectation there is that one has spent time going through the documentation.
