--- Comment #6 from Dave Jones <[email protected]> --- SPF is based on envelope-from domain. I see a lot of legit email where there is no A record for the envelope-from domain. Not sure if this is worth the effort. Is your SpamAssassin on an Internet edge mail filter? If so, setup Postfix with postscreen and weighted RBLs. I have about 20 RBLs weighted pretty well with score.senderscore.org helping out a lot. Greylisting with postwhite to exclude major mail hosting providers is essential when you turn up the sensitivity on the RBLs like this. It takes some time to tune all of this but once you do then you can sit back and admire the accuracy of your mail filtering without having to adjust scores constantly or reacted to new spam campaigns with custom rules. -- You are receiving this mail because: You are the assignee for the bug.
