How to flag SPAM in MS Exchange/Outlook using Mailscanner?

[Thiago Martins]

Hi folks.

Is there any possibilities to insert some header or any other way to
make Microsoft Outlook or Exchange know that a message is SPAM?

There is a folder in Outlook for SPAM and sometimes it flag some
messages as SPAM automatically. I believe this is done using some
header in the mail body.

Any ideas about that?

Sorry for my English and thanks in advance.
