Do you really use an ancient postfix with an not yet released dovecot, or is this a typo? > I have a child for whom I want to make an email account to which mail > can only be sent from email addresses in a whitelist hash file. Have a kook at http://www.postfix.org/RESTRICTION_CLASS_README.html. It would be something like this in main.cf: smtpd_restriction_classes = child child = check_recipient_access hash:/etc/postfix/childs_whitelist, reject # Probably you want this only on your submission port, or you # might become partly an open relay. To avoid this add '-o # smtpd_sender_restrictions=$submission_smtpd_sender_restrictions' # to your definition of submission in master.cf submission_smtpd_sender_restrictions check_sender_access hash:/etc/postfix/childs_access your childs email goes to childs_access: ch...@nicku.org child and the allowed recipients are collected in childs_whitelist: fri...@exmaple.org permit some...@example.net permit # allow every address with your domain nicku.org permit Don't forget to postmap the access tables: # postmap hash:/etc/postfix/childs_whitelist # postmap hash:/etc/postfix/childs_access This example is untestet but should work. But of course, you should not implement anything you do not fully understand. Dennis
