SUMMARY
To create send-only postoffices with the Microsoft Mail Multitasking MTA for Windows NT (NT MMTA) when you run the External Mail program as a service, use the Use WAN Drives check box in the Edit Service dialog box.



MORE INFORMATION
When the External Mail program is run as a service, it dynamically allocates three drive letters starting at the first available drive. Because these drives are not known at the time the External Mail program is run, the DrivesWAN option cannot be used.

To create send-only postoffices, check the Use WAN Drives check box. This option causes all postoffices in that instance to be send-only. For example, if this option is used with the below instance, the External Mail program will send mail to PO1-PO4, and it will not distribute the mail to the users on the destination postoffice, nor does it check the destination postoffice for outgoing mail. Another External Mail program must be running at the destination postoffice to assume these responsibilities.

[External-DrivesWAN]

DrivesUNC=\\server\po1

DrivesUNC=\\server\po2

DrivesUNC=\\server\po3

DrivesUNC=\\server\po4

When this instance is started, External will map drives E, F, and G (if this is the first instance, and E is the first available drive), where E is the home postoffice; F is used for sending, and G is for receiving mail. The External Service will apply DrivesWAN to the sending F drive.

Because all DrivesUNCs in a particular instance will have the DrivesWAN option applied, it will be necessary to create another instance for postoffices that are not send-only.
