DiscussionThere are two main uses for recipient filtering: preventing external senders from sending mail to particular mail-enabled recipients and preventing mail for nonexistent recipients from ever entering your Exchange organization.

Exchange returns the "550 5.7.1 Requested action not taken; mailbox not available" error when a message is submitted to a filtered recipient.
