genjitechhello 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 less04:04
genjitechthan 120sec. im running OSSEC with active-response firewall which does block any further attempts but all this happens before the block takes effect04:04
patdk-l2I don't see where anything you said would have ANY affect on what you want04:16
patdk-l2what does connection counts, errors, rates, ..., or even firewall blocks, have to do with number of emails04:16
patdk-l2you can send any number of emails over a SINGLE connection, upto the configured max04:16
genjitechthe 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 time04:19
patdk-l2I don't see where that is documented04:21
patdk-l2it says the error is incremented on a unrecognized or unimplemented smtp command04:21
patdk-l2doesn't say it is on user doesn't exist04:21
patdk-l2ah, it is documented in tuning, but not in rate limits04:23
patdk-l2http://www.postfix.org/postconf.5.html#smtpd_client_message_rate_limit04:25
genjitechi see. i was thinking that was to limit my clients sending rate.04:27
genjitechsorry i went back to reading the docs all over again. patdk-12 thank you for the help.04:47
