[Bug 5909] New: MIME_BASE64_TEXT catches valid Microsoft Outlook/ Exchange messages

https://issues.apache.org/SpamAssassin/show_bug.cgi?id=5909

           Summary: MIME_BASE64_TEXT catches valid Microsoft
                    Outlook/Exchange messages
           Product: Spamassassin
           Version: 3.2.4
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Rules (Eval Tests)
        AssignedTo: dev@spamassassin.apache.org
        ReportedBy: ralston@pobox.com


The MIME_BASE64_TEXT will fire on ham messages generated by Chinese
installations of Microsoft Exchange/Outlook.

I suspect this is the exact same problem as in bug 4687, but that more recent
versions of Windows/Exchange/Outlook prefer the gb2312 character set to the
big5 character set.

I don't seem to have privileges to mark this as a duplicate.  Bug #5553 is
about the same problem and has a much more general patch (the usefulness of
which is also demonstrated by comment #3 above).

I can confirm this bug with a ham e-mail using charset Windows-1252 and send
from a blackbery device.

Created an attachment (id=4316)
 --> (https://issues.apache.org/SpamAssassin/attachment.cgi?id=4316)
example ham that MIME_BASE64_TEXT catches

Note that I've changed the names/addresses and altered the Subject,
Thread-Topic, and thread-index headers to preserve privacy.  Otherwise, though,
I've kept the formatting of the message intact.

Created an attachment (id=4317)
 --> (https://issues.apache.org/SpamAssassin/attachment.cgi?id=4317)
suggested patch

The simplest way I can think of to fix the problem is to patch MIMEEval.pm to
exempt gb2312 (in addition to utf-8 and big5) from the MIME_BASE64_TEXT test.
