Hi all, I need to restrict a single user to internal e-mail addresses. Postfix docs say I need to do this: /etc/postfix/main.cf: smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/restricted_senders ...other stuff... smtpd_restriction_classes = local_only local_only = check_recipient_access hash:/etc/postfix/local_domains, reject /etc/postfix/restricted_senders: foo@domain local_only bar@domain local_only /etc/postfix/local_domains: this.domain OK matches this.domain and subdomains that.domain OK matches that.domain and subdomains I've done this (and adjusted the settings for the local environment), but the user is still able to mail outside his domain. Is there something I'm missing? Thanks Hans
