Sending or Posting using the Pickup Directory

If an SMTP or NNTP service is installed on the local computer, you can send or post messages using the pickup directory associated with the service. To send messages using the pickup directory, perform the following steps:

  1. Set the http://schemas.microsoft.com/cdo/configuration/smtpserverpickupdirectory or http://schemas.microsoft.com/cdo/configuration/nntpserverpickupdirectory field in the Configuration object's IConfiguration.Fields collection.
  2. Optionally, set the http://schemas.microsoft.com/cdo/configuration/flushbuffersonwrite field to True to avoid file system buffering. Setting this flag will impact performance, as each message must be written directly to disk. However, in the event of an interruption of service, messages will not be lost due to file system buffering.

These settings are defined for each SMTP and NNTP virtual service instance.

Dim iConf As New CDO.Configuration
Dim Flds  As ADODB.Fields
Set Flds  = iConf.Fields

' Set the configuration
Flds(cdoSendUsingMethod)           = cdoSendUsingPickup
Flds(cdoPostUsingMethod)           = cdoPostUsingPickup
Flds(cdoSMTPServerPickupDirectory) = "C:\InetPub\mailroot\Pickup"
Flds(cdoNNTPServerPickupDirectory) = "C:\InetPub\nntpfile\pickup"
Flds(cdoFlushBuffersOnWrite)       = True
Flds(cdoSendEmailAddress)          = """User"" <user@microsoft.com>"
' ... other settings
Flds.Update

Dim iMsg As New CDO.Message
Set iMsg.Configuration = iConf

' go on to use Message object
