The interface parameter may also be an interface group, an IP address, or a domain name. Listening can optionally be restricted to a specific address family, which can be either inet4 or inet6. The options are as follows: auth [<authtable>] Support SMTPAUTH: clients may only start SMTP transactions after successful authentication. Users are authenticated against either their own normal login credentials or a credentials table authtable, the format of which is described in table(5). From one of my conf's (using a credentials table): table secrets file:/etc/mail/secrets listen on eth0 port 465 smtps pki mydomain.com auth <secrets> match from auth for any action "relay" Good luck!
