OK, I solved it. The default load factor for queueing messages in
sendmail is:
# load average at which we just queue messages
#O QueueLA=8
which I changed to:
Ox20
(more appropriate to a 4 cpu ES40)
and restarted sendmail.
Size is apparently also a factor, but I haven't found where it's set
yet.
Thanks to Nikola Milutinovic for some useful insights.
Regards,
Peter
