Microsoft Forefront marks 'track' as SPAM

  • This weekend I had to send some mail, but the shared server that I usually use was blacklisted, so I set up an alternative SMTP-server on our dedicated host.

    Even from the non-blacklisted IP-address there still was an issue with KNews-mailings ending up in the unwanted e-mail of my Exchange-account when I send them with the scheduler, and not when I send them manually.

    The mailheader-difference was:
    X-Forefront-Antispam-Report: CIP:?.?.?.?;CTRY:?;IPV:NLI;EFV:NLI;SFV:SPM;SFS:
    versus
    CIP:?.?.?.?;CTRY:?;IPV:NLI;EFV:NLI;SFV:NSPM;SFS:

    I found out that the mails sent are sent differently by
    /wp-content/plugins/knews/direct/knews_cron_do.php
    which puts some tracking URL’s in the final mail.

    I commented out the foreach on line 97 to make this job send the mail equal to the manual mail, and the SPAM-score lowered to NSPM, so the mail ended up in my inbox again.

    As the visit-statistics are not visible in the free version I don’t think we will miss much, so a control to put the tracking off in the final mail would come in handy.

    Hello.

    About stats: it’s a bug. Update knews and you will get the new graphs.

    About SPAM:

    Are you commented the tracking pixel URL replacement?

    Please, check if you’re configured the htaccess:

    – Seeing the cat on Knews > Config > Advanced > tracking pixel

    – Once you’re seeing it, activate tracking pixel and try again the submission (uncomment the code before).

    Are you getting now low-score results?

    I activated the tracking pixel and uncommented the mentioned foreach.

    The result is again spam:
    CIP:?.?.?.?;CTRY:?;IPV:NLI;EFV:NLI;SFV:SPM;SFS

    If I comment out the foreach again the mail arrives right.

    So I’m afraid also the pixel-tracking modification of the URL’s is rejected by Microsoft’s Forefront.

    Probably SPAMmers also use KNEWS, or some tired receivers of ‘wanted’ messages still reject their knews-message as SPAM, instead of unsubscribing.
