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.
