Setup and configuration

Messages can come from a variety of sources. Handling replies to outbound email is a common case.

Currently there are these distinct paradigms for setting up return email:

1. A fixed outbound email address. FixedSenderEmail parameter defines the fixed email address used. Each package sending email can create and set its own FixedSenderEmail parameter. The default is to use ACS-Mail-Lite's parameter. As an originating SMTP agent, orignator is set to the ACS-Mail-Lite's parameter, if it is not empty. The replying email's message-id is used to reference any mapped information about the email, such as package_id or object_id. The message-id includes a signed signature to detect and reject a tampered message-id, and prevents publishing of system ids.
2. A dynamic originator address that results in a custom return email address for each outbound email. This provides an alternate way to supply the original message_id key, if the message_id key is altered. For this to work, the email system must be configured to accept email to any account at the domain specified by the BounceDomain parameter.
