Migrate to SMTPauth: temp reject for select users?
Situation: migrating from plain to authenticated SMTP. I have 2 Ironports, one doing outbound SMTP authentication, the other not yet. I would like the non-authenticated Ironport replying "no thanks you have to go to my authenticated brother" to selected users coming from the internal network, so we can move people to the new configuration gradually and check the progress. How should I proceed?
