Local aliases(5) that use ":include:" files are delivered by submitting a new message into the queue, addressed to the listed recipients. This "forwarded" message, could be subjected to milter processing. This may be on by default: https://www.postfix.org/postconf.5.html#internal_mail_filter_classes [ I don't see forwarding via local aliases mentioned as not actioned by default. ] So these should/may be subject to: https://www.postfix.org/postconf.5.html#non_smtpd_milters -- Viktor.
