Hello All! been a while since i have needed your help, but suggestions would be appreciated. Problem: Need to limit outgoing email attachments but still allow incomming email attachments. It seems like mime_header_checks will do this, however, i want to be able to selectively apply this. Right now, i use smtpd_restriction_classes to selectively apply whitelist/blacklist per user, could i add it to that? Is there a better way to restrict attachments outgoing only and restrict it based on user or destination address?
mime_header_checks apply to all mail within a postfix instance, so the easiest way to control this is to use separate postfix instances for internet incoming mail and user submitted mail.
