We have an email, company@example.com that when you send to it, it goes
out to the whole company. I would like to limit it so that only certain
accounts like "theboss@example.com" can send to it.
I have read http://www.postfix.org/RESTRICTION_CLASS_README.html and it
actually seemed simple enough but it doesnt work.



heres what I have in main.cf

smtpd_restriction_classes = insiders_only
insiders_only = check_sender_access hash:/etc/postfix/insiders,reject

smtpd_recipient_restrictions = permit_sasl_authenticated,
permit_mynetworks
reject_unauth_destination
reject_rbl_client relays.ordb.org
reject_rbl_client sbl.spamhaus.org
reject_rbl_client opm.blitzed.org
reject_rbl_client blackholes.wirehub.net
reject_rbl_client list.dsbl.org
check_recipient_access hash:/etc/postfix/protected_destinations


heres my protected_destinations:
company@example.com insiders_only

heres my insiders:
theboss@example.com

I have postmapped the 2 files and reloaded postfix.

Still anyone can send to company@example.com.
I also realize that the example in
http://www.postfix.org/RESTRICTION_CLASS_README.html was really to
restrict sending to an address from the outside and that part works.

thanks
