PMDF System Manager's Guide

The multithreaded SMTP client sorts outgoing messages to different destinations to different threads. The threaddepth keyword may be used to instruct PMDF's multithreaded SMTP client to handle only the specified number of messages in any one thread, using additional threads even for messages all to the same destination (hence normally all handled in one thread).

Use of threaddepth may be of particular interest for achieving multithreading on a daemon router TCP/IP channel---a TCP/IP channel that connects to a single specific SMTP server -- when the SMTP server to which the channel connects can handle multiple simultaneous connections.
