  • NoCeM, pl.* and false positives

    From Adam W.@21:1/5 to All on Sat Oct 21 21:10:01 2023
    Hi!

    I finally made the solution to repost cancelled articles to my local
    groups (chmurka.spam.*, available on news.chmurka.net). I process notices
    from three sources:

    - Eternal September
    - usenet.ovh
    - i2pn2

    I saw no false positives from Eternal September (great! But it might be
    also that they were already cancelled by usenet.ovh or i2pn2 and that's
    why I didn't catch them in Eternal September's notices), but considerable amount of them from usenet.ovh and i2pn2. Worth to take a look:

    i2pn2:

    <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]>

    usenet.ovh:

    <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]> <[email protected]>

    Since a few days, nocembot detect spam in all hierarchies.
    But i found a tipo in utf-8 spam d�tection messages.
    Please, tell me if you found new false positive.
    The goal is to reach 0% false positive like in fr and big8 hierarchies.

    Very nice! I save to a .mbox file that I scroll through, which can be monotonous but somewhat helpful.

    It looks like the rule I had set in spamassassin detecting empty posts
    probably accounts for most of these. (See discussion in e-s.support 'False positives in spam filter?'. I removed that rule yesterday.

    Considering we're sending out NoCeMs for close to 50,000 posts per day (yesterday was 50,746 for i2pn2), there could be a few false positives that
    I don't notice in the .mbox.

    It is VERY helpful that someone let's us (NoCeM sources) know if/when they
    see a few false positives. I've been pretty much dependent on only myself
    to try to make my filtering work well, so thanks for posting!
