    Spamassassin Marks Linuxforum Email As SPAM

    I found the Linuxforums email in my Junk folder the other day after Spamassassin updated the header as SPAM. Pretty ironic, n'est pas? The "culprit" is who sends Linuxforums' email. Distributed Checksum Clearinghouses ( received reports that this Email Service Provided has sent SPAM for clients other than Linuxforums. You can see some of their SPAM at Google group ( then search for priorityoneemail. As you know, Spamassassin can use DCC as part of it's rule set and, in this case, DCC's score tipped your email into the SPAM category for me. Perhaps you should consider changing vendors for sending the forum email. More detail below.

    Response from DCC:

    Was that linuxforums_org mail message bulk or subtantially identical
    to a bunch of other messages? It sounds likely and if so, then DCC did
    the right thing. Spam is unsolicited bulk mail. DCC detects bulk mail.
    To tell your DCC client [Spamassassin] that a particular stream
    of bulk mail is wanted or solicited, you should whitelist it.

    There is probably more to the story than that the linuxforums_org email
    is merely bulk. It is probably being reported as extreme bulk or likely
    spam with a target count "many" by an unwilling subscriber. Judging
    from your headers, the sender of that message was,
    which appears to be an email service provider or ESP. Most ESPs willfully
    and knowingly send substantial amounts of unsolicited bulk email or
    spam because they choose for competitive and profit reasons to not
    really discipline customers with dirty target lists. redirects to Cart & Ecommerce Software -
    and that web page waves all kinds of red flags for those who hate spam.
    The old, now defunct NANAS netnews group has reports of spam from See Google Groups (

    I also see that SMTP client or mail sender at
    [] as a very bulky DCC Reputation. See
    Query DCC Reputations for
    Poking at the distributed DCC database shows that has been sending mail that targets are saying is spam by reporting it to DCC with target counts of many. That could be because
    sends a lot of solicited bulk mail that DCC users have not whitelisted, but my guess based on experience with other outfits is that simply sends "gift subscriptions" or other unsolicited
    bulk email that it would insist is not spam several reasons on
