(FAQ) MDaemon 11.x: I am listed on a black list, what do I have to do to get off the blacklist?

I am listed on a blacklist site, what do I have to do to get off the blacklist?

There are many different reasons for being added to a black list; the most common reason being your server allows messages to be sent out from local addresses with no verification. Even though this isn't really technically a relay, some blacklist sites will flag your server for allowing mail from local addresses without first forcing authentication.

In MDaemon you can do the following:

  1. Click Security.
  2. Click Security Settings...
  3. Select SMTP Authentication on the left of the window.
  4. Check Authentication is always required when mail is from local accounts.
  5. Check Mail from 'postmaster', 'abuse', 'webmaster' must be authenticated.
  6. Click OK.
  7. Submit your site for re-testing at whichever site blacklisted you.

Note that this will require your users to enable outgoing authentication in their clients to send out mail through the MDaemon server. Our knowledge-base has a number of articles on how to setup various clients to do so, as referenced below. Note that WorldClient uses outgoing authentication by default.
