Can you please check these settings on your Exchange Server : http://technet.microsoft.com/en-us/library/dd277329.aspx
The error you are getting looks really close to what I used to face with my custom mail solution.
Maybe Admin of the Exchange server changed something or maybe it's the IP of your CRM Server, but I think the Exchange Server is culprit not CRM/Router.

This is something I have seen overlooked, which can cause this. Also are you running GFI Mail Essentials on the exchange box - if you are try putting your CRM server's IP in the white list .. that also has caused issues for some in the past.

As for why it may have been working fine then stopped working suddenly - could be the trust relationship with the machine you had it running on got broken in some way.
