We had some issues with spam, so created a smtp connector with IP [188.8.131.52] to clean up the queue.
Problem is, after i deleted the smtp connector and restated the smtp virtual server, all outgoing queues have "the remote server did not respond to a connection attempt" error.
I can telnet to each of the domains and send successfully, so no ports are blocked
I noticed in our firewall that the exchange server is still trying to connect to the IP I set for the smtp connector, even though it is already deleted.
I search the registry but there is no key for smtp connectors.
Created new connector to use DNS to route but still shows up on firewall as exchange trying to connect to [184.108.40.206] when processing queue.
I can do nslookup and ping each domain so it is doing DNS resolution set up correctly.
I ran SMTPdiag and it shows no issues, connects to each MX successfully.
Any idea what I should do?
