550 5.7.1 Unable to relay
Posted on 2006-04-11
Our Exchanger server works fine inside the office. When I try to setup employees outlook for individuals who are out traveling, they are able to receive mail but unable to send mail to anyone outside the domain. Am I just setting Outlook up incorrectly? When they send mail to outside the domain it just returns, 550 5.7.1 Unable to relay firstname.lastname@example.org.
I looked in the system manager and noticed under the protocols listed in the tree for my server name there was a listing for relay restrictions in the default virtual smtp server. I put a check box in "Allow all computers which successfully authenticate to relay, regardless of the list above."
What am I screwing up here?!!!!
