Emails sent from whitelisted senders
are blocked.
1. Whitelisted emails can be blocked if they contain content or attachments
that violate the Anti-Malware rules, since these have a higher order of
priority than the whitelist. Ensure that blocked emails do not violate Anti-
Malware rules.
2. Ensure that the filter priories are set so that the whitelist is above any
kind of filter that is catching the desired email. For more information refer
