Chapter 6 Device Security Settings Table 60 Device Operation > Device Configuration > Security > Anti-Spam > Lists > Add/Edit (continued) LABEL DESCRIPTION IP Address This field displays when you select the IP type. Enter an IP address in dotted decimal notation. IP Subnet Mask This field displays when you select the IP type. Enter the subnet mask here, if applicable. E-Mail Address This field displays when you select the E-Mail type. Enter an e-mail address or domain name (up to 63 ASCII characters). You can enter an individual e-mail address like [email protected]. If you enter a domain name, the device searches the source e-mail address string after the "@" symbol to see if it matches the domain name. For example, you configure a entry with "def.com" as the domain name. E-mails sent from def.com e-mail addresses such as "[email protected]" match the entry. E-mails sent from mail.def.com, such as [email protected] do not match the entry since "mail.def.com" does not match "def.com". You can also use a wildcard (*). For example, if you configure *def.com, any e-mail address that ends in def.com matches. So "mail.def.com" matches. 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. Header The device can check up to the first 63 characters of an e-mail's address. The whitelist or blacklist check fails for addresses 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 addresses 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 address. This field displays when you select the MIME Header type. Type the header part of an MIME header (up to 63 ASCII characters). In an MIME header, the header is the part that comes before the colon (:). Value 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. 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. Vantage CNM User's Guide 173
