Blacklisting

Blacklisting is the name given to a list of email addresses from which you specifically do not want to receive messages.

Each blacklist entry can be either a complete email address or a partial email address with Pattern matching characters The characters * and ? when used in an address or string. e.g. *@domain.com, bob@domian.*, etc.

The action taken when detecting a blacklisted address depends on whether the filter is being applied at the SMTP or domain level.

• SMTP
  The senders address and entire message will be rejected. Any bounce operations are handled by the sending server.

• Domain
  The filter policy specifies the action taken using the filter rules. See: Filter Rules
