All mail sent to my server gets refused, senders get error message:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

Please help!

Just to update:

it seems the problem is gone when SpamAssasin is off.
