Direct Mailer uses the same list of delivery locations for every job running, even when it is configured to use multiple delivery locations, such as drop directories or Simple Mail Transfer Protocol (SMTP) servers. Direct Mailer reads the list of delivery locations from the Administration database and is administered using Commerce Server Manager.

If the Delivery Method property is set to (2), Direct Mailer treats each entry in the list as a fully qualified path to the SMTP server pickup directory. If the Delivery Method property is set to (1), Direct Mailer requires each entry in the list to use the following format:

<SMTP server address>[: port]

Specifying the port is optional, but if it is not specified, Direct Mailer uses port 25.

When a Direct Mailer job is started, the first recipient in the direct mail list uses the first delivery location. The next recipient uses the subsequent delivery location. This delivery process is repeated until there are no new delivery locations. In this case, the delivery locations are recycled back to the first delivery location.

If a failure occurs in mailing, Direct Mailer does not retry another location, nor does it perform timeout or availability checking. Therefore, any given recipient can only use the delivery location that is assigned them. Direct Mailer also tracks the failures of a clustered DirectMailer database or failure of the drop point (SMTP or drop directory). For information about Direct Mailer availability and failures of a clustered DirectMailer database, see Direct Mailer.

To use multiple delivery locations

1. Expand Commerce Server Manager, expand Global Resources, right-click Direct Mailer, and then click Properties.
2. In the Properties dialog box, select Delivery Locations, and in the Selected Property Value box, type the fully qualified path to the drop directory or SMTP Server. Universal naming convention (UNC) paths are not supported.

   For multiple delivery locations, separate each location with either a comma or semicolon. The comma and semicolon are the only supported delimiters used to separate different paths.
