[Bug 7607] New: __HDR_ORDER_FTSDMCXXXX hits outlook express and windows live mail

https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7607

            Bug ID: 7607
           Summary: __HDR_ORDER_FTSDMCXXXX hits outlook express and
                    windows live mail
           Product: Spamassassin
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Rules
          Assignee: dev@spamassassin.apache.org
          Reporter: uhlar@fantomas.sk
  Target Milestone: Undefined

the __HDR_ORDER_FTSDMCXXXX rule catches mail sent from outlook express 6 and
windows live mail.
That further causes hitting HDR_ORDER_FTSDMCXX_DIRECT and
HDR_ORDER_FTSDMCXX_NORDNS in cases where client uses the mail client on local
network, without SMTP authentication, and without DNS (which may be quite
common in some organizations).

as a workaround, I recommend to add  && !ALL_TRUSTED to
HDR_ORDER_FTSDMCXX_DIRECT and HDR_ORDER_FTSDMCXX_NORDNS rules.

examples:

X-Spam-Status: Yes, score=9.781 required=5.6 tests=[ALL_TRUSTED=-1,
        FSL_HELO_NON_FQDN_1=0.001, HDR_ORDER_FTSDMCXX_DIRECT=1.999,
        HDR_ORDER_FTSDMCXX_NORDNS=3.5, HTML_MESSAGE=0.001,
        MIMEOLE_DIRECT_TO_MX=0.293, RDNS_NONE=1.274, TVD_RCVD_SINGLE=1.213,
        XPRIO_SHORT_SUBJ=2.5] autolearn=no autolearn_force=no
X-Mailer: Microsoft Windows Live Mail 16.4.3528.331
X-MimeOLE: Produced By Microsoft MimeOLE V16.4.3528.331


X-Spam-Status: Yes, score=9.154 required=5.6 tests=[ALL_TRUSTED=-1,
        DOS_OE_TO_MX=3.086, FSL_HELO_NON_FQDN_1=0.001,
        HDR_ORDER_FTSDMCXX_DIRECT=1.999, HDR_ORDER_FTSDMCXX_NORDNS=3.5,
        HTML_MESSAGE=0.001, MIMEOLE_DIRECT_TO_MX=0.293, RDNS_NONE=1.274]
        autolearn=no autolearn_force=no
X-Mailer: Microsoft Outlook Express 6.00.2900.5931
X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.6157

I can't attach full headers without permission of clients, will try if I get
access to client with either of those mail clients.

--- Comment #2 from John Hardin <jh...@impsec.org> ---
Also: this sort of thing is better discussed on the SA users mailing list (at
least initially).

I'll review masscheck results for those rules and if they won't hurt masscheck
performance I'll make the suggested change.

Outlook express ended production in June 2006.  I'm not sure how much weight we
can give to an email sent with it.

The issue is at HDR_ORDER_FTSDMCXX_NORDNS with __RDNS_NONE.

RDNS is an expected technology to setup a working mail server on the internet.

Fix that and you have nearly 5 point swing on your email as well as likely more
negative scoring rules will fire.
