All these msgs show up in the Imail Queue viewer tab?
Is you DNS ok? If you have doubts, point Imail at another DNS.

why?
Have you stop/start the SMTP service?

how many are you seeing in the NT task list?

ouch, these must be orphaned processes, perhaps scrogged by some
garbage msgs in the queue.

yes, I "think" 30 "should" be limit SMTP restricts itself to in
"normal" circumstances, that's why I think these 150 processes are
orphaned and need to be killed by the NT 'kill' command in the
resource kit, one by one, by pid number. or just reboot the box.
There are tons of "queue" hits in the KB. Happy reading.
5.00 is very old, 5.09 was the best of that release.
