Most likely your exchange is not setup correctly, I refer you to my earlier reply, have you checked those points yet? regards Peter *********** Maybe i should start from the beggining and try with your help to configure exchange the right way? I should start with my domain? may domain is a domain i have created from www.no-ip.com My Mx record is mail.domain.com. The name of the mailserver is MAIL, Right this far? I configured SMTP in the properties in the delivery tab -> advance button and in FQDN i have it like this mail.domain.com, and in the configure button i have my public ip adress setup. Is this right? Then i have in the recipients policies configured the default policies with my domain like this: @domain.com. And in the global settnings -> internet message format i have configured the default like this: domain.com I dont have any connectors configured etc. Sow that should do it or is this way wrong? And my router/firewall is configured to forward all request in port 25 for the public ip to the private ip on port 25 to the mailserver. Maybe i should try to connect the mailserver directly to the internet without a router/firewall to se if this is the problem. To bad i cant sen any screenshot to show you how it is configured.
