Im using SMTP Virtual Server in Win 2000 Adv Srv. behind the router. I opened port 25 for my computer. My ISP does not allow me to use port 25 except for their own smtp server. So I have to use their smtp server.
I do not have Exchange Server.
I configured my smtp virtual server to use my ISPs smtp server as smart host to forward all emails. But whatever I send via my smtp it goes to in badmail folder.
I tried telnet then I got this error message in badmail
Unable to deliver this message because the follow error was encountered: "This message is a delivery status notification that cannot be delivered.".
The specific error code was 0xC00402C7.
The message sender was <>.
The message was intended for the following recipients.
Please help me out
