Hi
My configurations is not standard beacuse:
master.cf:
smtp inet n - y - 100 smtpd
-o receive_override_options=no_address_mappings
In main.cf
I put all connections to local haproxy who called to 3 x amavis. And
amavis return to
xxx.xxx.xxx.184:10027 inet n - n - - smtpd
-o smtpd_proxy_timeout=900s
-o content_filter=
-o mynetworks_style=host
-o mynetworks=10.0.100.0/24
-o local_recipient_maps=
-o relay_recipient_maps=
-o strict_rfc821_envelopes=yes
-o smtp_tls_security_level=none
-o smtpd_tls_security_level=none
-o smtpd_restriction_classes=
-o smtpd_delay_reject=no
-o smtpd_client_restrictions=permit_mynetworks,reject
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o smtpd_end_of_data_restrictions=
-o smtpd_error_sleep_time=0
-o smtpd_soft_error_limit=1001
-o smtpd_hard_error_limit=1000
-o smtpd_client_connection_count_limit=0
-o smtpd_client_connection_rate_limit=0
-o
receive_override_options=no_header_body_checks,no_unknown_recipient_checks
....
In this place do you suggest adding a filter?
I thinking about postfwd (third party software) and check in like:
smtpd_data_restrictions =
check_policy_service { inet:127.0.0.1:10040 timeout=2s,
default_action=DUNNO }
reject_unauth_pipelining,
reject_multi_recipient_bounce,
permit
But it seems a little complicated
