We have exchange 2003 SP2 in our organization. It was working fine until Friday when a user reported that he is not receiving emails from outside. I tried to email from my gmail account to our exchange server and it received it but with a long delay. I restarted exchange server and everything running normally. Now it is delayin again. Is there anything that I can check to see where the message is delaying? I used both yahoo and gmail and both havent bounced back and they havent been received either.
