Exchange 2010 all messages getting stuck in queue with error 400 4.4.7
We had some power issues yesterday and while that normally wouldn't be an issue we are in the middle of changing our UPS equipment out. Needless to say servers we not powered down in a clean way. The exchange server came back up with the error that it had lost its trust relationship with the domain. I removed it from the domain and rejoined and that seems to bring email back up online.
Now this morning I am seeing that all of the outgoing messages to external domains are getting caught with the error above. Nothing has changed but i have a feeling it has to do with out send connector but I am not seeing any issues with it. Any help would be much appreciated.

Unable to telnet out, and email going through smarthost. I checked the outbound firewall rules and there is a rule allowing outbound 25 from internal to Any.
As far as event viewer goes, which logs should i be checking?

Please check internal emails.
Can you check your gateway/firewall is operational.
Run telnet mx1.hotmail.com 25 and check if you are able connect.
Also check if 25 port is open at firewall and ISP end.
