False Positive on DRUGS_STOCK_MIMEOLE rule

[Bob Proulx]

I have what appears to me to be a completely legitimate mail message
from a person who has the following in the mail header.

  X-Mailer: Microsoft Office Outlook, Build 11.0.5510
  X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106

That is triggering both __MIMEOLE_1106 and __MAILER_OL_5510 which
triggers DRUGS_STOCK_MIMEOLE for 3.5 points.  That seems to be an
overly agressive combination.  Should the rule be double checked?

Thanks,
Bob
