My postfix configuration is: Code: # See /usr/share/postfix/main.cf.dist for a commented, more complete versiondebug_peer_level = 2 # Debian specific:  Specifying a file name will cause the first # line of that file to be used as the name.  The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next li (Hardware)
