Hello All,
I have Exchange 2007 --- One Hub & CAS and another mail box server. Plast 7 years it never given me any trouble. Past two weeks mails are not going to outside domain and it is in the queue. I am able to receive and even able to send/receive within the domain.
I checked SMTP send connector, space, re-installed Hub & Cas, Disable firewall, AV etc...
After doing all these also, it is in the same situation.
Can someone help me?
Tonio
