[Bug 6256] New: Dynamic IP and Horde/IMP get tagged

https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6256

           Summary: Dynamic IP and Horde/IMP get tagged
           Product: Spamassassin
           Version: 3.2.5
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Rules
        AssignedTo: dev@spamassassin.apache.org
        ReportedBy: laas.toom@gmail.com


Spamassassin assigns the following score to legitimate e-mail sent with Horde
IMP from dynamic IP address:
X-Spam-Score: 2.599
X-Spam-Level: **
X-Spam-Status: No, score=2.599 required=5 tests=[RCVD_NUMERIC_HELO=2.599]

Headers hitting this test are similar to:
Received: from 26.47.191.90.sta.estpak.ee (26.47.191.90.sta.estpak.ee
    [90.191.47.26]) by webmail.edu.ee (Horde MIME library) with HTTP; Thu, 10
    Dec 2009 09:34:12 +0200

This HELO name is FQDN and should not hit the RCVD_NUMERIC_HELO header.

This relatively high score when coincident with other accident tests (e.g.
HTML_MESSAGE and TVD_SPACE_RATIO) blocks legitimate e-mail.

This behavior is reported by two different spamassassin setups one of which is:
FreeBSD
p5-Mail-SpamAssassin-3.2.5_4

And two different Horde/IMP setups one of which is:
Gentoo Linux
Horde 3.1.3
IMP 4.1.3

Yes, this was a bug in check_for_numeric_helo().  I believe we fixed it in bug
5878 which found its way into SpamAssassin 3.3.0.

On that aside:  SpamAssassin 3.3.0 has a bunch of updates to TVD_SPACE_RATIO
that would probably be of use to you in fighting that one.  HTML_MESSAGE
shouldn't have flagged anything unless you've increased its score from the
3.2.5 default of 0.001.  Be wary of adding points to that rule as it hits LOTS
of non-spam.


I'm marking this as a duplicate of bug 5878.  If you believe this is in error
and you can reproduce the bug with SpamAssassin 3.3.0, please re-open this bug.
