I've had problems in my network, since users use very weak
passwords and sometimes tend to respond emails where they ask for
your password, in order to use their email accounts to bombard
servers like Yahoo, Hotmail or Gmail, with messages spam, as
spammers putting on black lists.
Have you already set limits on the number of messages users can send
per hour/day? Typically, when an account is compromised, it will be
used to send way more messages than you'll find for a normal user
account. Setting a limit of 100 recipients per hour will be
sufficient for almost all users. Only those that have a legitimate
reason to send more messages get higher limits here, but the default
is fairly low.

Hi Arjen
I i going to set that in IMP config, and maybe set a limit to for the
# of destination per message.
Thanks for the suggestion, i am going to implement today, but i think
at the best for stop the spammer is implement captcha system in
compose window.
This three options, fix all the problem.
Thanks
Michel
