l 94f1b29917 refactor: do not copy the mail in memory for DKIM verification (#54) 
`String::from_utf8_lossy` always copies the data
for the case when it needs to replace invalid UTF-8,
but we don't want invalid UTF-8 anyway as replacing
invalid UTF-8 characters will break DKIM signature.

Jagoda Estera Ślązak 7d4fac698f fix(dkim): Make simple header canonicalization work properly (#53) 
Previously header parsing caused leading whitespaces to be
trimmed in HeaderBody, which resulted in incorrect simple
header canonicalization.

holger krekel cf96be2cbb feat: support self-signed chatmail relays (#855) 
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

Jagoda Estera Ślązak 4837754245 feat: Support addresses using domain literals (#42) 
If the incoming email comes from address that uses
domain literals `[<ipv4>]` or `[IPv6:<ipv6>]`,
skip DKIM verification and instead check IP
alignment with originating IP from XFORWARD
command.

Jagoda Estera Ślązak a096d0550f feat!: DKIM verifier (#35) 
* feat!: DKIM verifier

This implements a DKIM verification as well as a strict
DKIM signature alignment check with domain in `From`
header address.

Caches the retrieved RDATA using in-memory LRU.

BREAKING CHANGE: incoming messages now require DKIM signatures
  aligned to domain of the `From` header address.
