36.2.2.1 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 whitelist@ourcompany.com, 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.
36.2.2.2 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.
