Have a exchange 2010 which can recieve mail fine, but when sending out it complains.
I have setup an smtp connector (no smarthost)
and when an user sends a mail he gets a mail back saying that the mail address was not found!
The funny thing here is, there is 1 domain which i can send mail to, and this domain is actually used on google apps so it is outside our network.
The error i get is:
#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ##
oogling abit has hinted that this could be related to a permission issue?
