My mail server sends x-junkmail-status headers, an example value is "score=150/50, host=mx01.versatel.de". I also read about this in a maganzine. Reproducible: Always Steps to Reproduce: 1. 2. 3. Actual Results: . Expected Results: . .

Reporter: What are the "Expected Results" here? Did you know you can customize headers and filter on those? (see bug 16925, bug 61520, bug 109109)

If this was a standard header (e.g. agreed to among several antispam software developers, or the IETF), this would be a valid bug. I believe there is no such header standard, to date.

Expected result: When deciding if the message is a junk mail Mozilla takes the information in this header into account. A Google web search for x-junkmail-status gives 50 results, all from this year. Mail relay servers can guess if the message is junk or not by looking at how many mails with which content are sent by which server when. There also is a header X-Junkmail-Whitelist.

Take a look at bug 224318; there have been some changes made to look at some of these kinds of headers (from Habeas, SpamAssassin, SpamCatcher, or SpamPal). I don't think there's been a UI implemented for setting this stuff up, but you should be able to handle the problem. Reporter, do you know what spam filtering system is being used to generate the x-junkmail-status header?
