About Deny & Allow Lists

In the Allow & Deny Lists module you can define that emails from specific senders or domains are always quarantined (deny list) or delivered (allow list).


The Allow List is only used to categorize spam emails. If a sender is entered on the Allow List, his mails originally categorized as spam are delivered to the recipient as valid. If an email from a sender on the Allow List is classified as Content, Threat, AdvThreat or Rejected, it won’t be delivered.
