Disables IP verification by upgrading filtermail to v0.6,
changelog: <https://github.com/chatmail/filtermail/releases/tag/v0.6.0>
Messages using domain-literal addresses no longer require
to match the origin SMTP connection IP anymore.
This allows for example a relay using IPv4 email addresses
to send messages to other relays over IPv6.
This is not considering a breaking change as IP-address-only
relays are not considered a stable feature.

feat: support self-signed TLS via underscore domain convention
Domains starting with "_" (e.g. _chat.example.org) automatically use
self-signed TLS certificates instead of ACME/Let's Encrypt. The TLS
mode is derived from the domain name — no separate config option needed.
Internally, when config.tls_cert_mode is "self" (underscore domain):
- Generate self-signed certificates via openssl
- Set Postfix smtp_tls_security_level to "encrypt" (opportunistic TLS)
- Add smtp_tls_policy_map entry for underscore domains
- Skip ACME, MTA-STS and www CNAME checks in `cmdeploy dns`
- Serve /new via GET (not redirect to dcaccount:) with rate-limiting
(nginx limit_req, 2r/s burst=5)
- Return dclogin: URLs with ic=3 (AcceptInvalidCertificates) from /new
- Render QR codes client-side via JavaScript and qrcode-svg
- Use config.tls_cert_path/tls_key_path in Postfix, Dovecot and nginx
templates instead of hardcoded ACME paths
Deployments to test servers will not be cancelled anymore,
but it is not clear if we even want it.
This setup is much simpler because it only depends
on GitHub Actions features and does not allocate
a runner just to sleep there and wait in the queue.
