We have several users on the network and just one person cannot send an email out to a korean firm (in Korea). The error is From System Administrator/Subject: Undeliverable. The header shows that its not going past our domain. We have GFI spam blocker installed and the korean domain is not on our block list. I have put them on our whitelist. Also, when i send through webaccess, it works. Is there a setting in outlook or Exchange which might prevent emails from going out to a certain domain? Thanks.
