Filtering email content
Certain kinds of content embedded in email can be a security threat to your network. Other kinds of
content can decrease the productivity of your users. On the
POP3 Content
tab, you limit content types,
and block specified path patterns and URLs. You can use the asterisk (*) as a wild card.
Allow only safe content types
The headers for email messages include a Content Type header to show the MIME type of the email
and the MIME type of any attachments. The content type or MIME type tells the computer the types of
media the message contains. Select the check box for this feature if you want to limit the content types
that you allow through the proxy. When you select this check box, only the content types shown in the
text box are allowed. The format of a MIME type is
type/subtype
. For example, if you want to allow
JPEG images, you add
image/jpg
. You can also use the asterisk (*) as a wildcard. To allow any image
format, you add
image/*
to the list.

To remove a content type, select it from the list and click
Remove

message/*
or
multipart/*
because the POP3 proxy cannot work without them. If you try to
remove these content types you get an error message.

To add common content types to the list, select the MIME type in the
Predefined content type
column and click the
