If you submit mail over SMTP, you can get the Postfix queue ID (queue
file name) from the SMTP server's "end-of-data" response, avoiding
the need supply your own unique Message-ID header.
It you use Postfix 2.9 or later, you can enable long, non-reused,
queue IDs to simplify logfile analysis. Postfix may reuse an old
short queue ID after a message is deleted from the queue.
