InboxGuards Email Test

Email address check: syntax, MX, disposable and role account (no SMTP probe). Checks one address without sending mail: RFC syntax, whether the domain accepts mail (MX, null MX, implicit A/AAAA), disposable domain (CC0 list), role account (info@, support@...), free provider. Verdict ok / risky / undeliverable. No SMTP probe, so mailbox existence is not confirmed. Bad syntax: 400, never charged.
