 * lands in the configured IMAP mailbox via the port-config noreply identity,
 * and verifies the attachment bytes round-trip end-to-end.
 *
 * Requires:
 *   SMTP_HOST / SMTP_PORT / SMTP_USER / SMTP_PASS - outbound transport
 *   IMAP_HOST / IMAP_PORT / IMAP_USER / IMAP_PASS - inbound for verification
