The main requirement for this to work reliably is for queue-file
REC_TYPE_DONE records to never be used for purposes other than
finalizing actual recipients (I believe this is true today). If
Postfix were to use REC_TYPE_DONE for other purposes, or to finalize
recipients with a different record type, the archive daemon would
have trouble determining the message envelope.
As for delivery-agent vs. internal service, the internal service
approach is likely more robust. There should only be one archive
recipient per message. If someone wants more, that can be handled
via virtual(5) downstream.
