SMTP_A_B_C_D_E_F.tmp
When the driver is used to send a message, it creates one file with the naming convention SMTP_A_B_C_D_E_F.tmp where:
A is the process ID of the application that loads the driver.
B is the Siebel Communications API handle of the driver.
C is the Siebel Communications API handle of the service.
D is the time when the service is created.
E is the number of messages that this service sends.
F is the number of milliseconds that elapsed since the application was started.
This file is the encoded MIME message that is sent to the SMTP server
for delivery. This file is created under the bin/sent
directory unless you specify the Sent Email Directory profile parameter.
This file is deleted after the message is sent from the disk to the SMTP
server unless the Save Sent Msg profile parameter is set to True.
