[04:04] <genjitech> hello all, I'm having some trouble with rate limiting postfix 3.1.0 on Ubuntu Server 16.04.2 LTS.. I have customized /etc/postfix/main.cf with smtpd_error_sleep_time = 120s smtpd_soft_error_limit = 3 smtpd_hard_error_limit = 8 smtpd_client_connection_count_limit = 20 smtpd_client_connection_rate_limit = 10 .. and yet i still get slammed with single ips [49.140.10.140] dropping 1100+ emails to 3 different account in less
[04:04] <genjitech> than 120sec. im running OSSEC with active-response firewall which does block any further attempts but all this happens before the block takes effect
[04:16] <patdk-l2> I don't see where anything you said would have ANY affect on what you want
[04:16] <patdk-l2> what does connection counts, errors, rates, ..., or even firewall blocks, have to do with number of emails
[04:16] <patdk-l2> you can send any number of emails over a SINGLE connection, upto the configured max
[04:19] <genjitech> the address that are being to to dont exist and should fall under smtpd_soft|hard_error_limit yet that many getting through in such short time
[04:21] <patdk-l2> I don't see where that is documented
[04:21] <patdk-l2> it says the error is incremented on a unrecognized or unimplemented smtp command
[04:21] <patdk-l2> doesn't say it is on user doesn't exist
[04:23] <patdk-l2> ah, it is documented in tuning, but not in rate limits
[04:25] <patdk-l2> http://www.postfix.org/postconf.5.html#smtpd_client_message_rate_limit
[04:27] <genjitech> i see. i was thinking that was to limit my clients sending rate.
[04:47] <genjitech> sorry i went back to reading the docs all over again. patdk-12 thank you for the help.
