RELAY FOR INTERNAL SENDERS
Specify the authentication needed when a user sends an e-mail from inside the domain:
• Authentication or trusted IP required - When a sender is from the internal relay domain, the user
must be authenticated or be sending messages from a trusted IP.
• Authentication or trusted IP not required but only allow relay to internal recipients - When a
sender is from the internal relay domain, Authentication or trusted IP is only required when sending to
external domains.
• Authentication or trusted IP not required and allow relay to any addresses - When a sender is
from the internal relay domain, they can send to any domain even without being from a trusted IP. This
will act as an open relay providing the user is from an internal domain.
