smtp authentication

[chso]

Well you didn't explain that well...

1. If you send email for your domain, the SMTP server will accept them ALWAYS without any authentification as it's configured ( as long the mailboxes exist). This will not require ANY RELAY permissions, as the email final destination is your own server.

2. When you send email to gmail, you will require the email to be relayed, first accepted then pooled to be sent to gmail. For email relay you will need to authentificate otherwise spamers will abuse your server.
For SMTP authentification all you have to do is setup using email login/password same as imap/POP3.

Hope it helps and explains how it works. OK?
