I have set up my AppleShare IP 6.x mail server for ETRN so that mail is delivered on demand. I can see from the Mail Server Log that the AppleShare Mail Server is issuing the ETRN command, but it immediately disconnects from my ISP's mail server. Why?
DISCUSSION According to RFC 1985, ETRN works the following way: The host requesting mail delivery (the AppleShare IP Mail server in this case) connects to a mail server via SMTP and issues an ETRN command. The mail server receiving the ETRN command then initiates a new connection back to the requesting mail host. Therefore, once the AppleShare IP Mail Server issues the ETRN command to the ISP's mail server, the connection will terminate and it is up to the ISP's mail server to initiate a new connection to the AppleShare server and transfer mail. If you are having difficulty getting ETRN to work properly, the AppleShare Mail Log should tell you that (1) the ETRN command was sent, and (2) whether there was mail queued on the other mail server. If the log indicates that there is mail queued on the other mail server and you still don't receive any mail, verify that the external mail server can make an inbound SMTP connection to your AppleShare IP Mail Server. |
