Common errors

The user enters a full URL instead of a domain.

Fix: Use the bare domain name when checking MX records.

No MX records are returned and the user expects them to exist.

Fix: Check whether the domain uses direct A-record fallback or is simply not configured for mail.

The result is confused with TXT or SPF records.

Fix: Remember that MX records show mail servers, not email-authentication text records.
