The day-9 Gmail block that forced the 200/h hold is resolved: per-MX throttling shipped, Google is excluded entirely (MAIN_EXCLUDE_OPERATORS=google), and the OpenDKIM signing bug is fixed. With Google out of the mix, 400/h (~4k/day) is within the envelope these IPs cleanly sustained at 68-76% delivery with zero blocks. Lets the post-DKIM re-send backlog drain in ~1 day instead of ~3.
