This illustrates one of my complaints of most spam reporting (including for Razor). The basic idea people have is "I should report spam". THAT ISN'T ENOUGH. You have to report non-spam as well. If all that is reported is spam, then there is nothing to compare it against. You bias the system to recognize everything as spam and your false positives (non-spam classified as spam) soar (where 0.5% is too high).At 10:54 AM 5/22/2004, Peter Schuller wrote:

That should be fine.. Razor doesn't catalog the From: or To: addresses.
However, I'd be a little bit cautious if the mailing list is one that inserts stock advertising footers like this list does. Razor may wind up cataloging the footer if the text alignment for e4 winds up right, or if the message is empty other than the footer.
I don't know what the official policy here is, but I would urge you to report the non-spam mail with razor-revoke (a poor name, IMHO, as it implies that you only report spam) if you are going to report the spam via razor-report.
That way, if there is a portion of the message that is not really relevant to the spam (such as the footer on this message), it will get enough votes as non-spam that it isn't considered a sign of spam.
This also helps with the issue that some people may report as spam, say, Apple's (or another legitimate mass mailing) monthly mailings to people on its list. Some people will consider that as spam and, rather than get off the list, will report it as spam. Others that may want that mail will then have the message flagged as spam, if no one is reporting it as non-spam.
While I can affect the mail filtering to the people on my floor of my building, I don't control the mail to my parent organization. They have (wrongly, in my opinion) set things up so that a message reported as spam by razor gets a spamassassin score of about 6, which is well into what I would consider very probably spam. The problem is that I have seen too many false positives by razor for me to feel comfortable with it to allow it to be prosecutor, judge, jury, and executioner.
So, PLEASE, if you report spam, then also report ham. (and, of course, only do this with mail that you personally have reviewed).
