23.2.2.1 Zone to Zone Anti-spam Rule Example
This example shows how to configure (and display) a WAN to DMZ anti-spam rule to scan
POP3 and SMTP traffic. SMTP spam is forwarded. POP3 spam is marked with a spam tag.
The ZyWALL logs the event when an e-mail matches the DNSBL (see Section 23.2.4 on page
215 for more on DNSBL). The white and black lists are ignored.
23.2.3 White and Black Lists
The following table identifies values used in these commands. Other input values are
discussed with the corresponding commands.
Router(config)# anti-spam rule 1
Router(config-as-rule-1)# activate
Router(config-as-rule-1)# from-zone WAN
Router(config-as-rule-1)# to-zone DMZ
Router(config-as-rule-1)# scan smtp
