Unable to send external mail on server 2003
I have managed to succesfully (or not as the case might be) setup ActiveSync on exchanger server 2003 through the IIS manager. Although the active sync is working i now have a problem as follows;
1) i can receive e-mail from external sources.
2) I can send and receive mail from internal address's.
I no longer can send out mail to external address, i think this is a problem with name resolution?
PS prior to setting up the activesync all was working well.
Please can anyone help
