Quick notes on running Rspamd in a Podman pod

This includes three containers:

• Rspamd itself, for use as a Postfix milter
• redis
• unbound (because rspamd's DNSBL lookups will likely fail when using public or your provider's DNS, see https://www.rspamd.com/doc/faq.html#resolver-setup).

Ideally, all of this should work in both rootless and rootful mode.
