Tony, While I was trying to troubleshoot my mass-mail performance issue some years ago, I talked with IBM and learned a lot about the internal workings of the SMTP server. The bottom line is (as far as I could determine): It works as designed, if you restrict yourself to having no more than one email per SPOOL file. Of course, there's nothing in the code or the doc that prevents you from packing more than one email into a single SPOOL file. However, the more emails you have per SPOOL file, the worse the performance gets. The SMTP server was written at the time when IBM added TCP/IP support to MVS. It was written in PASCAL at that time, and it was written as a single-task server. If you need something better / faster / more powerful, you might want to check out the UNIX (OMVS) - based email programs. Documentation and Redbooks about that are available at IBM.
