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.Maybe you can use tarpit? Or implement AUTH? Limit the number of recipients? Those are ideas to make spammer life a little bit hard, but if the spamming software is smart (and patience), even on that condition it can send lots and lots of SPAMs. What about add SpamAssassin checks on the outgoing messages? You can even integrate it with LDAP, razor and pyzor.
