I seemed to have more spam getting through. When I look at those messages which I think should have been caught, I observe that many\/most\/almost all of them contain in the X-Spam-Status the value: RCVD_IN_DNSWL_HI=-5. Spamassassin is giving them a whopping -5 whole points if the dns source of the message appears in the High Reliability list of the site DNSWL.org, which according to what I read, is one of those sites that maintains reputation lists, and says of the High list: <\/p>\n\n\n\n
“Recommended Usage: Skip spam filtering for medium and high ranked IPs. These are trusted to send spam rarely enough that they are not worth filtering.”<\/p>\n\n\n\n
There is some discussion on the net, others too seem to think they are getting a lot of spam because of this, suggesting that a site on the dnswl high list can be induced to forward spam. I know little of all of this, but I have added a rule to \/etc\/spamassassin\/local.cf: <\/p>\n\n\n\n
score RCVD_IN_DNSWL_HI 0 -0.1 0 -0.1<\/code><\/pre>\n\n\n\nThis changes the value from -5 to -0.1. If I set it to 0 (as I originally did) then I can’t tell in X-Spam-Status whether the rule applied or not. Now I see the rule in X-Spam-Status with a small value. <\/p>\n\n\n\n
So far this seems to have helped. Encouraged by this, I’ve added another couple of specifications to \/etc\/spamassassin\/local.cf, to wit: <\/p>\n\n\n\n
ok_languages en fr
ok_locales en fr<\/p>\n\n\n\n
Which should act to increase the “spaminess” score of emails in other languages and character sets. A couple of mail users are French speakers, but AFAIK nobody using tarragon for mail speaks any other language or\/and receives mail in another language. <\/p>\n","protected":false},"excerpt":{"rendered":"
