- This is under control of the 'OY' option definition. If you have
- defined the 'Y' option, try commenting out that option in sendmail.cf
- (then rebuild a freeze file if used, and kill and restart the daemon).
-
- Without OY, sendmail should serialize queue processing. You would
- only get 150 connections if you ran the queue so often that you
- had 150 concurrent queue runs.
