You can blacklist sender email addresses or whole domains.
Actamos will not perform any checks on emails originating from blacklisted senders and will block emails instantly.
Actamos supports domain level and mailbox level blacklists.
Domain level blacklists always take precedence over mailbox level blacklists. In other words, if a sender is blacklisted on a domain level, such sender will not be able to send email to any of the mailboxes on the given domain.
A sender cannot be blacklisted and whitelisted at the same time.
In the Activity Log you can see which emails have been blocked because of the blacklisting. Such emails are marked with a special icon.
