These 4 mail-discovery hostnames were silently caught by the wildcard
(* 60 IN A 108.61.23.129), resolving to the docker host instead of
the mail server. CNAMEs to mail.supported.systems make their resolution
explicit and follow the mail server's A record automatically.
Mail server migration cutover. mail.supported.systems flips inbound mail
for all 20 MX-referring zones to the new server. old-mailu.supported.systems
preserves a name pointing at the old IP (66.42.75.247) during the
migration window for IMAP drain, mailbox sync, and parallel verification.
Decouples the 6 dependent services (dignity.ink:kayla, septic.report:permits,
supported.systems:{docs, *.docs, mcbluetooth, s120}) from the legacy host
record. Services now follow the new-canonical .supportedsystems.net naming
and resolve directly to the new docker host.
Bulk swap of the old docker host IP to the new one across 13 zones.
docker-1.supported.systems intentionally preserved at the old IP — the
hostname stays tied to the old box until decommissioned.
27 records across 15 zones converted from direct A records pointing at
the Tailscale endpoint (100.79.95.190) to CNAMEs pointing at the
Tailscale-named alias. Now if the underlying Tailscale node's IP
changes, only the rpm-bullet record needs updating instead of
chasing 27 zones.
Affected zones (all *.l labels + a handful of dev / dev.mary names):
acrazy.org copper-springs.online demostar.io flonhoney.com
homestar.ink kg7q.cc malloys.us ourjob.site
qubeseptic.com ryanmalloy.com septic.report sidejob.pro
supported.systems warehack.ing zmesh.systems
No CNAME collisions: none of the converted names had other records
(MX/TXT/SRV/CAA/AAAA) at the same exact name. _acme-challenge.<sub>.l
records sit at distinct subdomains and continue to resolve independently
(verified: TXT lookups for known _acme-challenge.l.* names still return
the original values).
Also fixed prepare-zones.sh: added `|| true` after the serial-detection
grep so a zero-match (first run of a new day) doesn't trip `set -e`
and abort the whole prep.
