    Hello

    I need some configuration tips for Postfix.
    What I`m locking for is a moderate configuration, witch just filters out the worst.

    The server has about 3000-4000 e-mail users.

    Would you recommend using blacklist?
    Witch rbl/dns sites should I add/are safe to use?

    I have implemented some rate limits

    Code:
    smtpd_error_sleep_time = 1s
    smtpd_soft_error_limit = 10
    smtpd_hard_error_limit = 20
    This should be ok?
    It`s important that these rules don`t make trouble for clients.

    I`m also thinking of implementing some of these limits

    Code:
    smtpd_client_connection_count_limit
    smtpd_client_connection_rate_limit
    smtpd_client_message_rate_limit
    smtpd_client_recipient_rate_limit
    smtpd_client_new_tls_session_rate_limit
    smtpd_client_event_limit_exceptions
    But I need some tips as what to configure here.
    I do not want to make trouble for my clients, only give them a better service :)
