2026-06-09Switch mail container from SES relay to direct deliveryyyamashita-6/+2
Port 25 outbound is no longer blocked on Hetzner, so SES relay is unnecessary. Remove relayhost, SASL auth config, and libsasl2-modules. Postfix now delivers directly to recipient MX; inet_protocols=ipv4 already present to avoid IPv6 PTR issues. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-06-01Configure Amazon SES relay for Postfix (port 25 blocked by Hetzner)yyamashita-2/+6
SES credentials are injected via .env file (not committed). entrypoint.sh creates sasl_passwd at runtime from SES_ACCESS_KEY_ID / SES_SMTP_PASSWORD. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
2026-06-01Fix milter IPv4 binding and container DNS for MX lookupsyyamashita-2/+2
- opendkim.conf / main.cf: localhost → 127.0.0.1 (getent がIPv6を優先し Postfix の inet_protocols=ipv4 と競合していた) - docker-compose.yml: dns: 8.8.8.8/1.1.1.1 を追加 (Docker embedded DNS が MX クエリを解決できなかった) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
