Hello.
I got a note that some of the senders (not all though), get the following error after sending their emails:
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:
G@nospam.com unrouteable mail domain "nospam.com"

It seems that the Exim MTA has a trouble routing. Can it be some anti-spam protection?
Any ideas regarding this problem?
Thanks in advance.
