Read a domain’s published email records

This asks public DNS for two records a domain publishes about its own mail: its DMARC policy at _dmarc.<domain> and its SPF record at the domain itself. It quotes back what is published and states the published meaning of each field. It sends no mail, touches no mailbox, and makes no claim about whether anything can be forged.
