Hi!
 
I am receiving every 5 minute some messages in the RAW Queue (now there are 35 messages) where the content is:
"root@localhost
(reason: 553 5.5.4 <OTRS@localhost.localdomain>...Real domain name required for sendere address)
(expanded from: root@localhost)"
 
How can I resolve this problem?

Regards,
