Verify how inbound email is routed for a domain.

MX priorities, targets, Null MX declarations and safe SMTP reachability checks.

Missing MX, unreachable targets and explicit no-mail domains are presented differently.

FAQ

What does lower priority mean?

Mail senders try lower MX preference values first.

What is Null MX?

A single MX 0 . record states that the domain does not accept mail.
