eSlider e1208be24e chore(mail): pinned-version update check off, Gmail postscreen whitelist, docs
- compose: ENABLE_UPDATE_CHECK=0 (image intentionally pinned to DMS v15.1.0).

- postscreen: permit Google SMTP outbound ranges (Gmail retries from rotating IPs,

  '450 PASS NEW' never completes) — keeps LinkedIn/Gmail mail out of the tarpit.

- README: DNS/ops notes; user-patches: whitelist copy path.
