The Anti-Spam Status Screen - ZyXEL Communications ZyWALL USG 300 User Manual

Chapter 35 Anti-Spam
For the best anti-spam performance, use only the most accurate DNSBLs that you
can. Adding other (less accurate) DNSBL domains can decrease the anti-spam
performance. Some DNSBLs are more effective than others. You want the DNSBLs
that catch as much spam as possible while avoiding false positives (identifying
legitimate e-mail as spam). Different DNSBLs also have different usage policies.
For example, you can check http://www.spamhaus.org or https://www.sorbs.net
for more information.
