SUMMARY

The ETRN command is supported in Microsoft Exchange Server 5.0 Service Pack 1 and later. It is also supported in Exchange Server 5.5. If you are unable to receive Simple Mail Transfer Protocol (SMTP) messages using the ETRN command, apply the latest Exchange Server 5.0 service pack or upgrade to Exchange Server 5.5.

MORE INFORMATION

The ETRN command is an Extended SMTP (ESMTP) command that causes an ESMTP host to send messages to a particular domain. When an Exchange Server computer sends the ETRN command to an ESMTP host, the host sends any messages that are waiting to be sent to recipients in the specified domain. Older versions of Exchange Server cannot send the ETRN command.
