* dovecot: enable login names with square brackets * config: make IPv4-only relays use self-signed TLS certs * postfix: make delivery for IP-only relays work * cmdeploy: skip DNS checks for IPv4 only relays * www: generate dclogin codes for IPv4-only relays * opendkim: disable DKIM signing on ipv4-only relays * get delivery working * get tests working on IPv4 only machine * doc: document IPv4-only relays * dns: warn if mail_domain is an IP, instead of checking DNS * config: validate domains when formatting them * ci: add cmlxc testing for no-DNS relays * ci: run no-dns and normal CI in parallel * retain "config.mail_domain" as the domain part of @ email addresses, so for ipv4 relays "[1.2.3.4]" and introduce config.ipv4_relay and config.mail_domain_bare helpers. * ci: migrate from --no-dns to --type ipv4 for cmlxc compatibility * cleanup dead code, fix docs, fixate cmlxc version --------- Co-authored-by: missytake <missytake@systemli.org>
