Postfix limits and rbl
 
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 :)

Take a look at http://www.howtoforge.com/block_spam..._level_postfix (also check out the comments below the tutorial as some of the blacklists don't work anymore).
