Windows Server 2008 SMTP Server can hold mail for clients that connect periodically to download messages. In this case, the client issues an ATRN command. The Simple Mail Transfer Protocol (SMTP) service then starts to send messages to the ATRN domain. You can create a remote domain for an address for which your virtual server queues messages and enable ATRN for the domain.
To enable ATRN transmissions for a remote domain
Expand the SMTP virtual server, and then click Domains.
In the results pane, click the remote domain you want to change. On the Action menu, click Properties.
Click the Advanced tab, and then select the Queue messages for remote triggered delivery check box.
Click Add or Remove as necessary to select Windows user accounts that will be allowed to use the ATRN command in this domain.
