Module: MailAuth::Domain

Defined in:
lib/mailauth/domain.rb

Overview

One spelling for a domain name, so two of them can be compared. An internationalized domain travels both as the U-label a person reads (münchen.example) and the A-label DNS and DKIM's d= carry (xn--mnchen-3ya.example); comparing those byte-wise fails DMARC alignment on perfectly good mail.
