unkinben 5b3058e75e fix(postfix): use hash: transport_maps with postmap init container
- Splits hash-type map files into a separate postfix-maps ConfigMap
- Adds postmap init container that builds .db files from all maps into
  a postfix-db emptyDir, which is then subPath-mounted per map in the
  main container
- Updates transport_maps in main.cf to hash:/etc/postfix/transport

unkinben ebc21b9fa1 fix(postfix): use .unkin.net subdomain pattern in transport map
per transport(5), .domain matches all subdomains. main.unkin.net was
an exact-match entry; .unkin.net covers it and any future subdomains.

unkinben d57c1db5f8 fix(mailgateway): pin postfix-external LoadBalancer to 198.18.199.1 2026-05-24 19:54:08 +10:00
unkinben 942e23c146 fix(mailgateway): add purelb dmz service-group annotation to LoadBalancer 2026-05-24 19:52:16 +10:00
unkinben b09cd1628d feat(postfix): deploy postfix MTA and rspamd spam filter
- mailgateway namespace with Deployment + HPA (2-6 replicas)
- rspamd Deployment + HPA (2-6 replicas) with milter interface
- postfix configured to relay inbound mail to stalwart via transport maps
- rspamd milter on port 11332 for spam scanning and DKIM signing
- DKIM keys stored in Vault at kubernetes/namespace/mailgateway/default/dkim-keys
- TLS cert via cert-manager (vault-issuer) for mail.main.unkin.net
- rspamd web UI exposed via Traefik Gateway at rspamd.k8s.syd1.au.unkin.net
- postfix external LoadBalancer service for inbound MX on port 25
- Add full main.cf and master.cf as ConfigMap resources mounted via subPath
  - main.cf: relay-only gateway config, texthash: transport maps, rspamd milter
  - master.cf: standard smtp + submission (587, TLS required) + internal processes
- MAILNAME/MY_NETWORKS/MY_DESTINATION env vars kept in sync with main.cf
- LOG_TO_STDOUT=1 for k8s log collection
