Hi Bastian, Although I cannot claim high expertise, I do know (hopefully well enough) my setup! :) So, the end server (vmail2) runs postfix and dovecot. However, all the logs I have posted are from the gateway server (mailgw1) and are indeed postfix and amavis only. Postfix (at mailgw1.noa.gr) receives mail from the internet, it forwards it to amavis (localhost:10024), then amavis forwards it back to postfix (localhost:127.0.0.1:10025) which eventually delivers to vmail2.noa.gr. So the logs I posted are from these three phases. Here are the associated listeners (postfix is listening at port 25 via postscreen): tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 1257592/postscreen tcp 0 0 127.0.0.1:10024 0.0.0.0:* LISTEN 1064531/amavisd (ma tcp 0 0 127.0.0.1:10025 0.0.0.0:* LISTEN 1257631/smtpd tcp6 0 0 :::25 :::* LISTEN 1257592/postscreen tcp6 0 0 ::1:10024 :::* LISTEN 1064531/amavisd (ma And postfix master.cf: ============================================================================================ # ========================================================================== # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) # ========================================================================== #smtp inet n - n - - smtpd -v smtp inet n - n - 1 postscreen smtpd pass - - n - - smtpd dnsblog unix - - n - 0 dnsblog tlsproxy unix - - n - 0 tlsproxy #submission inet n - n - - smtpd # -o smtpd_enforce_tls=yes # -o smtpd_sasl_auth_enable=yes # -o smtpd_client_restrictions=permit_sasl_authenticated,reject #smtps inet n - n - - smtpd # -o smtpd_tls_wrappermode=yes # -o smtpd_sasl_auth_enable=yes # -o smtpd_client_restrictions=permit_sasl_authenticated,reject #628 inet n - n - - qmqpd pickup fifo n - n 60 1 pickup cleanup unix n - n - 0 cleanup qmgr fifo n - n 300 1 qmgr #qmgr fifo n - n 300 1 oqmgr tlsmgr unix - - n 1000? 1 tlsmgr rewrite unix - - n - - trivial-rewrite bounce unix - - n - 0 bounce defer unix - - n - 0 bounce trace unix - - n - 0 bounce verify unix - - n - 1 verify flush unix n - n 1000? 0 flush proxymap unix - - n - - proxymap smtp unix - - n - - smtp # When relaying mail as backup MX, disable fallback_relay to avoid MX loops relay unix - - n - - smtp -o smtp_fallback_relay= # -o smtp_helo_timeout=5 -o smtp_connect_timeout=5 showq unix n - n - - showq error unix - - n - - error discard unix - - n - - discard local unix - n n - - local virtual unix - n n - - virtual lmtp unix - - n - - lmtp anvil unix - - n - 1 anvil scache unix - - n - 1 scache retry unix - - n - - error proxywrite unix - - n - 1 proxymap smtp-amavis unix - - n - 2 lmtp -o smtp_data_done_timeout=1200 -o smtp_send_xforward_command=yes -o disable_dns_lookups=yes -o max_use=20 127.0.0.1:10025 inet n - n - - smtpd -o content_filter= -o local_recipient_maps= -o relay_recipient_maps= -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_data_restrictions=reject_unauth_pipelining -o smtpd_end_of_data_restrictions= -o mynetworks=127.0.0.0/8 -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,no_milters ============================================================================================ Cheers, Nick
