Explanation:

Forces servers to abide by Domino 5 rules to resolve conflicts between Allow and Deny list entries in the SMTP inbound relay controls.

• 0 (default) - Entries in the Allow field of the SMTP inbound relay controls take precedence over entries in the Deny fields when there is a conflict between them. For example, given the following entries:
  Deny messages to be sent to the following external Internet domains: xyz.com
Allow messages only from the following Internet hosts to be sent to external Internet domains: relay.abc.com
the host relay.abc.com can always relay to any destination, including destinations in the domain xyz.com.
  
• 1 - Entries in the Deny fields of the SMTP inbound relay controls take precedence over entries in the Allow fields in the event of a conflict. Using the preceding example, if you deny relays to xyz.com, the host relay.abc.com cannot relay to the denied domain.
