Chapter 6 Device Security Settings Table 60 Device Operation > Device Configuration > Security > Anti-Spam > Lists > Add/Edit (continued) LABEL DESCRIPTION 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. Apply Cancel The device 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 device 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 device would only check up to the first three characters of the e-mail subject.
