If the request is made in SMTP, like this: RCPT TO:<recipient@rcpt-domain> NOTIFY=SUCCESS,... Then it is possible to fix this with smtpd_command_filter. http://www.postfix.org/postconf.5.html#smtpd_command_filter has examples. Let me know if you need help with this solution. Explaining this takes time, and I don't want to do it if your problem is something else. Wietse
