I have the following in main.cf
unknown_address_reject_code = 554
unknown_hostname_reject_code = 554
unknown_client_reject_code = 554
smtpd_recipient_restrictions =
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
permit_mynetworks,
check_client_access hash:/etc/postfix/pop-before-smtp,
check_sender_access hash:/etc/postfix/access_list,
check_recipient_access hash:/etc/postfix/access_list,
reject_non_fqdn_hostname,
reject_unknown_client,
check_relay_domains
This is blocking a lot of spam and unwanted mail, but there are two sites
that we want to receive mail from that are also being blocked -- I
contacted their sys admins to get them to fix their systems, and they said
it would take them a while to determine the problem and fix it.
These two sites are being rejected with a "554 Client host rejected: cannot
find your hostname" error.
Can I add a add a line in main.cf, above the other checks, for:
check_sender_access regexp:/etc/postfix/access.regexp
and then put in the access.regexp file:
/gbod.com/ OK
/ecomc.com/ OK
Will this allow the two sites I want to allow, while still keeping all the
other blocks in place.
Thanks!
Larry
