Sometimes messages are going to be blocked because of intermittent problems. Dropped/corrupted packets, network outages, software glitches, and automated MITM attacks out on the open internet can all result in one-off scenarios where a data packet gets flagged and dealt with according to the receivers security policy. The internet is designed to be fault tolerant because packets of information break all the time. Resend and try again. Note that you didn't mention if subsequent emails continued to fail - You encountered a single failure, made a change, and noticed a difference. So now you have no way to isolate the problem. You should have just asked them to resend to the same address. We can't really troubleshoot based on the information provided. Attempting to discern why a single email failed is like finding a needle in a haystack. Sure, it can be done, but all you are going to find is a needle and is that really what you should be looking for right now? -Ben
