DNS is fully automatable: Hestia (cp.carrierone.com, zone owner = justin user)
is the DNS master, HE.net are slaves. Added google-site-verification TXT (id
14464) via v-add-dns-record as root; verified resolving on public resolvers +
HE.net slaves. Owner just clicks Verify in the Postmaster console. Documents the
v-add-dns-record path for future records.
Documents the 2026-06-18 reputation incident (snowshoe -> Gmail domain-rep
blocks, RBLs all clean), the single-IP-per-stream consolidation, and
fill-in-the-blanks setup steps for Google Postmaster Tools, Microsoft SNDS/JMRP,
and Yahoo CFL (all require owner account login + HE.net DNS). Plus ongoing
hygiene + how to re-expand IPs once reputation recovers.
