MajorLinux 9c62e7f804 Logwatch fleet article: add cloud-image config-drift section 
Documents three more patterns surfaced in the 2026-05-10 fleet-mail
investigation, all hitting hosts derived from cloud images or
cross-provider migrations:

- Packer/snapshot-leftover myhostname (postfix EHLO + message-id
  identifies the build artifact, not the production hostname; remote
  spam scorers hate it)
- Empty relayhost silently routes mail via the public MX instead of
  the Tailscale-internal path, exposing it to spamchk that internal
  traffic bypasses
- Stale SASL passwd map referencing a missing file from a previous
  external-SMTP relay setup, deferring every send with "local data
  error"

Each looks benign in isolation. Together they made dcaprod's Logwatch
disappear into spamchk for weeks while showing 250 OK on the source.
