Blacklisting and whitelisting in Zimbra

Blacklists and Whitelists:-

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. To add blackist or whitelist entries to your salocal.cf.in file, simply add lines in the following format:

vim /opt/zimbra/conf/salocal.cf.in

blacklist_from sales@traveloforange.com
whitelist_from bill@yahoo.net
blacklist_from *@emn-mysavingsnow.net

Note that * is a wildcard. In this example *@emn-mysavingsnow.net indicates all email from any user at emn-mysavingsnow.net.

When you are finished editing the salocal.cf.in file, restart Zimbra spamassassin by issuing the following command at the server prompt (as the zimbra user):

zmmtactl restart && zmamavisdctl restart
