Thanks for the answer. However, as a IT support guy, our bosses will always
ask why their mails are spammed and sometimes they insist to know the exact
algorithm. I search microsoft sites and couldn't find any useful at the
moment. Can any microsoft expertise give us some clue?
Except for open-source anti-spam software, you really expected any author of
proprietary software to divulge its inner workings, especially so spammers
could use that information to thwart that particular anti-spam solution?
Does your company produce software? If so, do they also release the
Functional Spec (for design) and Engineering Spec (for QA testing) to their
customers? No, they give the customer an user manual.
Try calling your own ISP as see if they will divulge the exact algorithms
they employ to block spam. Obviously that information could be used to
thwart their scheme if it were known in detail.
Why does your company even bother with the Junk Filter in Outlook? That is
a guessing scheme based on Bayes weighting of keywords and, for Outlook,
uses a database that is NOT based on the user's personal history of e-mails
but on a sampling that Microsoft decides to push out once per month to their
Outlook users. If this is for a company, the spam solution should be
implemented up on the company's mail server, not at the clients. Because
all e-mails transferred by the company's mail server should be considered
important, company workstations should have the Junk Filter option disabled
in Outlook along with those workstations not employing any other anti-spam
solution. As far as the company is concerned, all e-mails delivered by the
company's mail server are important to their employees. Filtering should be
done up at the mail server.
