I notice
] 3.3.2 ENVID
This looks very interesting; but seems to fail to explain how it
might be set and/or read. Am I missing something?
] The ENVID (envelope identifier) is a tag that is primarily for use
] within Delivery Status Notifications (DSN), so that the Bounce
] Address (RFC2821.MailFrom) recipient can correlate the DSN with a
] particular message. [RFC3461] The ENVID is therefore used from one
] message posting, until the directly-resulting message deliveries.
] It does not survive re-postings.

] The format of an ENVID is free-form. Although its creator might
] choose to impose structure on the string, none is imposed by
] Internet standards. By implication, the scope of the string is
] defined by the domain name of the Bounce Address.
