Configuring ATRN for Remote Domains
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1
The SMTP service can hold mail for clients that connect periodically to download messages. In this case, the client issues an ATRN command. The remote Simple Mail Transfer Protocol (SMTP) service then starts sending messages to the ATRN domain. You can create a remote domain for an address that periodically reviews messages and enable ATRN for the domain.
Important
You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /User:Administrative_AccountName "mmc systemroot\system32\inetsrv\iis.msc".
Procedures
To enable ATRN transmissions for a remote domain
In IIS Manager, expand the SMTP virtual server, and then click Domains.
In the details pane, right-click the remote domain you want to change, and 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.
