  • Greylisting can only be used as an anti-spam defense if the Gateway is connected directly to the Internet enabling communication with unrecognized senders.
  • To avoid messages from trusted sources being greylisted, add them to a White List.
  • Only senders with Suspicious or Bad TRUSTmanager reputations can be greylisted.
