Windows Server 03
Heres an odd one, I think its a sporadic DNS issue but maybe not. They are complaning that people are sending them messages and they never receive them.
I email a client, they never recieve the message. I email them again and they receive it.
I check their Exchange logs and sure enough the 1st message is nowhere to be found.
I check out my logs and it looks like it went through, however, its missing the server domain name. You can see it on the last line of the logs. Check it out.
heres the one that did not go through
and here is the one that did
Any ideas what could cause that problem?
