Help recieving external mail on Exchange 5.5

[patelbg2003]

Hi Guys

I can send and recieve across my exchange site. I can recieve external mail but I cannot send any emails out. Every time I try I get a msg in outlook saying

Your message did not reach some or all of the intended recipients.

Subject:
Sent: 15/04/2003 13:32

The following recipient(s) could not be reached:

'patelbg@' on 15/04/2003 13:32
The recipient name is not recognized
The MTS-ID of the original message is: c=GB;a= ;p=Arab Bank;l=ITI01-030415123212Z-147

I'm kinda lost on why this would happen

Regards

Bhavesh

DNS I would assume...unless you're using a smart host?
Can you resolve domain names from the mail server?

On your connections tab, what do you have for Message Delivery? Are you using DNS?

Solved it, Mailsweeper seemed to be cause of the problem. It did not like the IP address of the exchange server

Thanks
