any help much appreciated..
We have a C160 that currently monitors and delivers incoming email without a problem. We are now trying to setup Outgoing Email monitoring and are encountering the above problem when trying to send emails. We have setup the Mail Connector in our Exchange Server 2007 to send email to the Ironport and we can see messages accumulating in the Ironport queue.
But they don't go anywhere due to the above "error". We have configured the Ironport to use our internal DNS Server and have the correct Default Gateway set.
Can anyone please shed any light on why the messages are not going out.?
(We have disabled the Exchange Server Mail Connector to the Ironport for now so messages continue to be delivered direct out of Exch07 server to the internet but would really like to be able monitor outgoing emails)
Again, any help would be appreciated
cheers
Mark
