Mail Exchanger (`MX`) Reachability Probe
Email Address Internationalization (`EAI`) Readiness Check
Check whether an organization's Mail Exchangers (`MX` records) advertise `SMTPUTF8` support for internationalized email addresses containing Unicode or regional characters (`mgbh0fb@example.ug`).
Non-Destructive EHLO Handshake:Our inspection resolves priority `MX` records and opens a temporary TCP connection on port 25, sending `EHLO pulse.dnsforum.ug` to verify if the server returns `250-SMTPUTF8` in its capability advertisement. No emails are sent during this measurement.
