Can someone PLEASE!!!! help me with this error????? This is Ex2k on my home network. I can send mail internally and to the outside without any problems. I'm unable to recieve any mail from the outside from any of my accounts. .net 007: This e-mail message was undeliverable due to the following reason: .net 018: Each of the following recipients were rejected by a destination mail system. Note: The reasons given by the destination mail system are included to help you determine why each recipient was rejected. Solution: Attempt to resend, or contact the recipient by alternate means to let them know about the issue. Recipient: <marvc@xxxxxxxxxx> Reason: 5.7.1 Unable to relay for marvc@xxxxxxxxxx I've published the mail server via port 25 on my router, the IP address of the Default SMTP Virtual Server Properties is set to the internal ip of the server with logging enabled. Connection Control is set to "Only the list below" and includes the IP address of the internal DNS server for the domain. Relay is set to "Only the list below" and includes the IP address of the internal DNS server for the domain. Do I need to add the ip address of the internal email server also? I'm currently using the Default Recipients Policy which has the SMTP & X400 @domain.com types already configured. Should I create a new recipient policy? Any help on this is appreciated.
