Thanks for the feedback and the POP clarification. I will check into other
POP daemons. You say:
" I prefer to accept within limits then tell users that they will not
receive until they clean up their act. "
I agree with this. Does sendmail actually allow for this? How do you notify
the user that they will not receive further messages until they clean up
their act?
Sincerely,
- Henrik
