[ALUG] Outlook 15 and false positives in Spamassassin.

[Andreas Tauscher]

Outlook.... again....
This software is driving me crazy.

Ususal Microsoft adds an X-MimeOLE header to a sent email.
But not always. And to make it really nice:
If it is added depends on:
* Version
* Web or local
* Are other X- headers set.


Outlook 15 now is also really in-consequent in adding this header.
If a mail is set to high priority the header X-MSMail-Priority is added
(why my dear friends in Redmond? There exists a Priority header. OK it
is a non standard header: X-Priority. But it is in use since at least 8
years before the first version of Exchange and Outlook was released. Ah,
but was defined by others making it not acceptable for Microsoft...)
then it does not add the X-MimeOLE header.
If in a mail sent from a MS software and the X-MimeOLE header is missing
Spamassassin is honouring this with 1.9 points.

To fix this add to /etc/spamassassin/local.cf:

header   __HAS_OFFICE15_IN_MAILER     X-Mailer =~ /^Microsoft (?:Office
)?Outlook 15\.0/
meta     MISSING_MIMEOLE        (__HAS_MSMAIL_PRI && !__HAS_MIMEOLE &&
!__HAS_SQUIRRELMAIL_IN_MAILER && !__HAS_OFFICE15_IN_MAILER)
describe MISSING_MIMEOLE        Message has X-MSMail-Priority, but no
X-MimeOLE
