I still can not found a good solution for preventing outgoing SPAM,
I am stock in a server where local users start to send spam, and the
only bad solution that currently I have found is to cancel the
account, but this after hundreds of email have been send.
I would like to know if there is an smtp proxy or an alternate
software to qmail-ldap/patch that can help to prevent this kind of
SPAM, I have seen that some sites have a protection based on messages
sent per day, but would like to know how to implement something
similar. I would like to avoid canceling accounts and just relay on a
SMTP limit per users so thatI I do not have to worry ir a users tries
to send 10000 or emails.
any ideas to solve this will be appreciated.
