ERROR 554; sender address rejected - when forwarding message through Exchange 2003 server
Posted on 2009-05-14
I am trying to set up a forward, and usually this has not been a problem, but now things are bugging. So far I have successfully been able to forward from the user account the forward has been set to (eg user1). I used user1's mailboks and sent a message to email@example.com with a succesful forward to firstname.lastname@example.org.
However, when I send a message from an external mail to email@example.com the message bounces back with the following message:
<myserver.mydomain.com #5.5.0 stmp;554 <firstname.lastname@example.org>: sender address rejected: Access denied>
Under my exchange server I have checked that "Internet Message Formats" is set to allow forwarding. No luck
Under the mydomain.com connector, I have removed the smart host and use my own dns. No luck
Under SMTP VS, I have removed relay restrictions and connection restrictions. No luck
Can anyone give me a solution as to what may be wrong since the mail server is accepting a mail sendt from mydomain.com the be forwared to the new external mail account, but not an external mail sent to the domain?
