we run exhcnage server and our customer company xyz runs exchange. one of our employees TOM cannot receive any emails from company xyz. i have checked and we have no problems with any other employees receiving emails from company xyz. Tom received emails from all other domains, yahoo, msn, etc with no problems.
I told compan xyz to see what the problem is on their end. I check our exchange server for message tracking center and there is no trace of receiving emails from company xyz to TOM.
I even setup a pop3 for testing on my home computerwith the same name and email as one of the xyz company employees. that email successfully was received in TOMs email.
I assume it's company xyz. any suggestions or thought would be helpful.
