MIME headers
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 will often insert comments into header values or
leave them blank. These malformed headers can fool some spam and virus filters.
You can use the MIME headers list to mark email from certain bulk mail programs or
with certain types of content that are common in spam messages. You can choose to
mark the email as spam or clear for each header you configure.
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 protection profile action is
taken. If no match is found, the email is passed on to the next spam filter.
You can use Perl regular expressions or wildcards to add MIME header patterns to
the list. See
“Using Perl regular expressions” on page 354
.
Note:
MIME header entries are case sensitive.
