well, nothing can really prevent you from bad users with valid logins you can only mitigate the amount of spam until you recognize what happens and you shut down the user account the problem with webmail and such limitations is that you have always the same client-ip and if the values are too low it affects users which are not responsible for spam so the solution is get rid of untrustable users and/or force them at least to use a mail-client from their own IP/machine anvil_rate_time_unit = 1800s smtpd_client_connection_rate_limit = 50 smtpd_client_recipient_rate_limit = 400 smtpd_recipient_limit = 100
