Header This field displays when you select the MIME Header type.
Type the header part (beginning with “X-”) of an MIME header (up to 63 ASCII
characters).
In an MIME header, the header is the part that comes before the colon (:).
For example, if you want the whitelist or blacklist entry to check for the MIME
header “X-MSMail-Priority: Normal”, enter “X-MSMail-Priority” here as the MIME
header.
Value This field displays when you select the MIME Header type.
Type the value part of an MIME header (up to 63 ASCII characters).
In an MIME header, the part that comes after the colon is the value.
For example, if you want the whitelist or blacklist entry to check for the MIME
header “X-MSMail-Priority: Normal”, enter “Normal” here as the MIME value.
Subject This field displays when you select the Subject type. Enter up to 63 ASCII
characters of text to check for in the e-mail headers. Spaces are allowed.
You can use a wildcard (*). For example, if you configure “*good”, any e-mail
subject that ends in “good” matches. So “this is very good” and “this is not so good”
both match.
The wildcard can be anywhere in the text string and you can use more than one
wildcard. You cannot use two wildcards side by side, there must be other
characters between them.
The ZyWALL can check up to the first 63 characters of an e-mail’s subject. The
whitelist or blacklist check fails for subjects over 63 characters. However, a
whitelist or blacklist entry that uses some text followed by a wildcard only requires
the ZyWALL to check the number of characters before the wildcard. So the check
would still work for subjects longer than 63 characters. For example, if you used
“abc*”, the ZyWALL would only check up to the first three characters of the e-mail
subject.
