Use this command to configure email filtering based on the MIME header. MIME
header filtering is enabled within each protection profile.
The FortiGate unit compares the MIME header key-value pair of incoming email to
the list pair in sequence. If a match is found, the corresponding action is taken. If
no match is found, the email is passed on to the next spam filter.
MIME (Multipurpose Internet Mail Extensions) headers are added to email to
describe content type and content encoding, such as the type of text in the email
body or the program that generated the email. Some examples of MIME headers
include:
• X-mailer: outgluck
• X-Distribution: bulk
• Content_Type: text/html
• Content_Type: image/jpg
The first part of the MIME header is called the header key, or just header. The
second part is called the value. Spammers often insert comments into header
values or leave them blank. These malformed headers can fool some spam and
virus filters.
