23.2.3.1 White and Black Lists Example
This example shows how to configure and enable a white list entries for e-mails with
“testwhite” in the subject, e-mails from [email protected], e-mails with the Date
header set to 2007, and e-mails from (or forwarded by) IP address 192.168.1.0 with subnet
255.255.255.0.
23.2.3.2 Regular Expressions in Black or White List Entries
The following applies for a black or white list entry based on an e-mail subject, e-mail address,
or e-mail header value.
• Use a question mark (?) to let a single character vary. For example, use “a?c” (without the
quotation marks) to specify abc, acc and so on.
• 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.
• The ZyWALL checks the first header with the name you specified in the entry. So if the e-
mail has more than one “Received” header, the ZyWALL checks the first one.
23.2.4 DNSBL Anti-Spam Commands

headers against DNS (Domain Name Service)-based spam Black Lists (DNSBLs). You must
