That way, inbound 8bit mail will not fail DKIM signature checks. One way to do that is to tweak the master.cf file to match the below: $ postconf -P '*/inet/enforce_mime_input_conversion' smtps/inet/enforce_mime_input_conversion = yes submission/inet/enforce_mime_input_conversion = yes $ postconf -Mf pickup/unix cleanups/unix pickup unix n - n 60 1 pickup -o cleanup_service_name=cleanups cleanups unix n - n - 0 cleanup -o enforce_mime_input_conversion=yes [ Your service name for wrapper-mode SMTP on port 465 may be "submissions" or just "465", ... The "cleanups" service entry is a clone of the "cleanup" entry with a tweak. ] If you have a dedicated submission server, or a separate Postfix instance for submission, then there's no need for such master.cf tweaks. -- Viktor. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
