Recipient Blacklist

The Recipient Blacklist 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 blacklisted on a per domain basis or globally (applied to all MDaemon domains). The Recipient Blacklist 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 blacklisted addresses, listed by the domain that is blacklisting them.

Domain

Choose the domain with which this blacklisted 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 blacklist the address globally.

Email address

Enter the address that you wish to blacklist. 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.
