SPF good senders domain list

Apr 8, 2008, 5:04 AM

Post #1 of 5 (3464 views)

When we run spam checks for incoming mail , I would like to skip spam
checks if mail is SPF passed and mail is from ( A well known bank , my
travel agent .. etc etc )

Curently I use USER_IN_SPF_WHITELIST , but I have to maintain a list of
"good" domains myself. It will be good if we can have a colloborative
good list

Is there a shared list of trustable domains that can be looked up ( via
DNS preferably )

Thanks
Ram

http://www.dnswl.org/ is one such. You'll need to inspect what their
definition of 'trustable' is of course, in the same way as you would
when considering whether to use a given DNSBL.

Maybe <http://www.habeas.com/>, <http://www.isipp.com/>, or
<http://www.domain-assurance.org/> offer something you can use.

But DNSWL lists all domains. I want only domains that have SPF records
and are trustable

So check DNSWL after an SPF PASS.
