DNS name whitelisting
INSERT INTO whitelist_dnsname (_whitelist,_description) \
VALUES ('%.mweb.co.za','# whitelist *.mweb.co.za');
INSERT INTO whitelist_dnsname (_whitelist,_description) \
VALUES ('%.mail.mud.yahoo.com','# whitelist all yahoo mud
mailservers');
INSERT INTO whitelist_dnsname (_whitelist,_description) \
VALUES ('n10.bulk.dcn.yahoo.com','# whitelist only this mailserver');
DNS name whitelisting works as follows:
[logwall01][/]# host web32804.mail.mud.yahoo.com
web32804.mail.mud.yahoo.com has address 68.142.206.34
[logwall01][/]# host 68.142.206.34
34.206.142.68.in-addr.arpa domain name pointer
web32804.mail.mud.yahoo.com.
The forward and reverse DNS *must* match otherwise it will not work.
If forward and reverse dns match, then the whitelisting can work.
..
DNS whitelisting refers to the connecting MTA's hostname. If you want to
whitelist
a domain part of the email address, you would use sender whitelsiting.
