The Content Type Filtering screen lists the content
types that are allowed or denied by this filter.
Allow Content Types:
Use this option if you wish to accept most content
types, but only want to reject a few specific types. To allow or deny
incoming messages based on their content types, complete the following
steps:
-
Select the Allow content types radio button to
allow multipart messages to be routed onwards. If you wish to
allow all content types, you do not need to select any of the
MIME types in the list.
-
To deny multipart messages with certain MIME or DIME types as
parts, select the checkbox next to those types. Multipart messages
containing parts of the MIME or DIME types selected here will be
rejected.
Deny Content Types:
If you wish to block multipart messages containing
most content types, but want to allow a small number of content types,
select this option. To reject multipart messages based on the content
types of their parts, complete the following steps:
-
Select the Deny content types radio button to reject
multipart messages. If you wish to block all multipart messages, you
do not need to select any of the MIME or DIME types in the list.
-
To allow messages with parts of a certain MIME or DIME type, select
the checkbox next to those types. Multipart messages with parts of
the MIME or DIME types selected here will be allowed. All other
MIME or DIME types will be denied.
MIME and DIME types can be added by clicking the MIME/DIME
Registered Types button. The next section describes how to
add, edit, and remove MIME/DIME types.
