The simplest filtering methods for spamassasin are the blacklist and whitelist. Blacklist entries block all email from an address or domain, and whitelist entries bypass all filtering for an address or domain.

Restart Zimbra spamassassin by using following command.

[zimbra@mail root]$ zmmtactl restart && zmamavisdctl restart
