Virus, botnet and user's bad policies about password allows many 3rd party entities to stole passwords, in the last month i've experienced a grows of hacked users, and in some case many spam messages are sent from my servers before i can block the user.
I've tried many combination smtpd_client_message_rate_limit smtpd_client_recipient_rate_limit anvil_rate_time_unit config options but as the sender changes frequently the client, sending from different locations, so the limits above has no effect and i can't stop the spammer. Does exists any configuration to limit the # of sasl login from an user? It could be very useful, and cloud be also useful monitor many login of the same sasl user from different ip. What do you thing about that? -- /*************/ nik600 http://www.kumbe.it
