I am trying to create a Content Filtering rule, using wildcards, that will delete ALL incoming emails that mention a particular domain in the header text.
E.g.: Delete all incoming email with the text [*.click] in the Return-Path header.
What I've done (that isn't working):
Create a rule called "Blacklist"
Match type "ANY condition must be met"
Enable wildcards ON
Action: Delete Message
Condition: contains specific words or phrases
Field: Email header
So for this header example,
do I need wildcards on both sides of the phrase, like this? [*.click*]
Thanks for your help!
