Postfix implements DSN as specified in RFC 3464. The Postfix command-line interface and interaction with VERP are described at http://www.postfix.org/DSN_README.html You can also use the smtpd_command_filter to force SUCCESS notification. The following is based on the examples in http://www.postfix.org/postconf.5.html#smtpd_command_filter /etc/postfix/main.cf: smtpd_command_filter = pcre:/etc/postfix/command_filter /etc/postfix/command_filter: # Forced success notification /^(RCPT\s+TO:\s*<.*>.*)\s+(NOTIFY=NEVER.*)/ $1 $2 /^(RCPT\s+TO:\s*<.*>.*)\s+NOTIFY=(\S+.*)/ $1 NOTIFY=SUCCESS,$2 /^(RCPT\s+TO:.*)/ $1 NOTIFY=SUCCESS,FAILURE Wietse
