MikeL's FreeBSD howto - mail/AUTH

This is basically a checklist of how to make sendmail AUTH work. The intent is not to cover everything in detail, merely to point you to each of the tasks that must be performed.

AUTH is the mechanism that allows client email programs to relay their outgoing SMTP data through this server with username/password authentication, thus preventing having to hardcode IP addresses in your mail config, and allowing mobile/roaming users with changing IP addresses to relay.

You can use sasldb2 for authentication, to add users use:

        saslpasswd2 -c username

If you want to enable SMTP AUTH with the system Sendmail, read
Sendmail.README

NOTE: This port has been compiled with a default pwcheck_method of
      auxprop.  If you want to authenticate your user by /etc/passwd,
      PAM or LDAP, install ports/security/cyrus-sasl2-saslauthd and
      set sasl_pwcheck_method to saslauthd after installing the
      Cyrus-IMAPd 2.X port.  You should also check the
      /usr/local/lib/sasl2/*.conf files for the correct
      pwcheck_method.
