The Recipient Block List is located at: Security » Security Settings » Screening. This list contains email addresses that are not allowed to receive mail through your server. If a message arrives for an address on this list, it will be refused. Addresses may be blocked on a per domain basis or globally (applied to all MDaemon domains). The Recipient Block List operates on SMTP envelope RCPT data only (not message headers).
Messages are refused if they are to addresses listed here
This window displays all currently blocked addresses, listed by the domain that is blocking them.
Domain
Choose the domain with which this blocked address will be associated. In other words, what domain do you wish to prevent from receiving mail for the specified address? Choose "All Domains" from this list to block the address globally.
Email address
Enter the address that you wish to block. Wildcards are accepted, therefore "*@example.net" will suppress any message for any user at "example.net", and "user1@*" will suppress any message for any address beginning with "user1@", regardless of the domain to which the message is addressed.
