All mailboxes were deleted.
Now, when trying to send an Email from the server (command line. Either ‘mail’ or ‘mutt’), to firstname.lastname@example.org the message is not being sent, and this is the /var/log/maillog for the relevant message:

Sending mails to an outside address has no problems.
The thing is, that the firstname.lastname@example.org should also be considered as an outside address, and it doesn’t.
Some additional data:
mydestination = $myhostname, localhost.$mydomain
(I tried even removing this line, or manually changing it, but the errors remain.)
The old.com domain name is located on a different server, with a different IP address.
Is there any idea regarding a possible solution or at least other examinations directions?
