Horse Tools 1.3.40

• The mail checks no longer draw conclusions from an address the site does not really send from. Sites behind a proxy, a load balancer or a container runtime see 127.0.0.1 or a 10.x where the public address should be, and judging either the sender policy or the reverse name against that answers a question about a machine which does not exist on the internet.
• It mattered more than it sounds. The sender-policy check could evaluate a private address against a record ending in "reject everything else" and print a confident accusation that happened to be right for the wrong reason — and would have been wrong the first time it met a host whose real address was authorised. It now says it cannot tell, which every screen already knows how to show.
• The Email screen states the address mail leaves by, and the name that address carries. Half the checks on that screen are about it, and when it is unknown they are skipped — which is a different thing from passing, and now reads as one.
