Hi,
anvil_rate_time_unit = 60
smtpd_client_connection_rate_limit = 6
smtpd_client_connection_count_limit = 4
smtpd_client_connection_limit_exceptions =
/etc/postfix-in/smtpd_client_connection_limit_exceptions
smtpd_client_event_limit_exceptions =
/etc/postfix-in/smtpd_client_event_limit_exceptions
smtpd_soft_error_limit = 2
smtpd_hard_error_limit = 4
mynetworks = cidr:/etc/postfix-in/mynetworks
mynetworks_style = host
$ cat /etc/postfix-in/mynetworks
127.0.0.0/8 OK
10.0.0.0/8 OK
172.16.0.0/12 OK
192.168.0.0/16 OK
$ cat /etc/postfix-in/smtpd_client_connection_limit_exceptions
$mynetworks
[...]
$ cat /etc/postfix-in/smtpd_client_event_limit_exceptions
$mynetworks

$
But still:
Error: too many connections from 172.20.16.26
Why?
$ postconf mail_version
mail_version = 3.4.13
$ lsb_release -ds
Ubuntu 20.04.3 LTS
$
Thank you!
