My goal is to limit outbound email to only three domains. All other email
destined for any other domain should be redirected to a single, valid
internal mail box.
It isn't working. Email to addresses outside this domain are still being
delivered.
/etc/postfix/access:
domain1.com OK
domain2.com OK
domain3.com OK
. REDIRECT valid@email.address
main.cf (changes from default):
mydomain=domain1.com
myorigin=$mydomain
inet_interfaces = all
mydestination = $myhostname, localhost.$mydomain, localhost
relayhost = mailhost.domain1.com
# Sender restrictions:
smtpd_sender_restrictions =
reject_non_fqdn_sender
reject_unknown_sender_domain
check_recipient_access hash:/etc/postfix/access
permit_auth_destination
reject
# Recipient restrictions:
smtpd_recipient_restrictions =
reject_unauth_destination
check_sender_access hash:/etc/postfix/access
reject_invalid_hostname
reject_non_fqdn_sender
reject_non_fqdn_hostname
reject_unknown_sender_domain
reject_unauth_pipelining
reject_non_fqdn_recipient
reject_unknown_recipient_domain
permit_mynetworks
reject

And I receive the email at addr...@domain.that.shouldntgetemail.org.
Ive been digging through every post about white lists and blocking
domains. Im sure this is either an order thing or a fatfinger or something
equally stupid but Im getting no errors from postfix either at startup or
mail processing.
Could anyone please offer any solutions?
Thanks!
