Platform SDK: CDO for Windows 2000

Setting the Send and Post Method

With the Message object, you have the option of choosing how messages are sent or posted for delivery. These options depend on the software installed on the computer that is running your Microsoft Collaboration Data Objects (CDO) application. The following table lists these methods and describes when each method is available.

Method	Description
Pickup Directory	If the application is running on a computer that has installed Simple Mail Transfer Protocol (SMTP) or Network News Transfer Protocol (NNTP) services, you can use that services pickup directory.
Network using SMTP or NNTP	You can connect directly to an SMTP or NNTP service and use SMTP or NNTP, respectively, to send or post a message.

To set the send or post method for messaging objects, perform the following tasks:

Set the http://schemas.microsoft.com/cdo/configuration/sendusing and http://schemas.microsoft.com/cdo/configuration/postusing fields to the desired method in the associated Configuration object. The methods listed in the previous table are identified with enumerations CdoSendUsing and CdoPostUsing.
Set any required or optional configuration fields that correspond to the send or post method.

The required and optional fields depend on the send or post mechanism.
