Partial Deployments – not all users need Failsafe mailbox

Is it necessary to configure every single user on the Email Security Failsafe service?

No – there are a number of configuration options to choose from, as follows:

• Most deployments of the Email Security Service will configure the majority of their users with a Failsafe mailbox.
• When setting up the service, the administrator will specify a Bounce Message Recipient. This address will receive any bounce messages sent by the system as a result of a missing mailbox, alias or distribution list, thereby giving the Administrator the opportunity to create the missing address or simply ignore the bounce.
• It is also possible for Administrators to configure a catch-all email address into which any unrecognised emails will be placed.
