Technitium's split-horizon rewrites *.viktorbarzin.me to 10.0.20.203
(Traefik LB) for the 192.168.1.0/24 Barzini WiFi (TP-Link router has
no hairpin NAT). The rule is name-agnostic so mail.viktorbarzin.me
(and imap./smtp.) get sent to .203 too — where Traefik does not
listen on 25/465/587/993. iOS Mail on Barzini WiFi silently hangs
while Roundcube (port 443 via Traefik) keeps working.
Adds pfSense NAT rdr rules so traffic to 10.0.20.203:{25,465,587,993}
gets redirected to 10.0.20.1 (the mail HAProxy listener already
serving the public path). Loaded on every incoming interface by
pfSense rule generation, so any LAN/VPN client falling into the
split-horizon answer lands on the right service unchanged.
Includes idempotent reproducer script (mirrors the existing
pfsense-haproxy-bootstrap.php pattern) and the networking.md
mail carve-out paragraph plus the stale .200 → .203 reference.
