MX Lookup
Look up MX records.
See which mail servers accept email for a domain, in priority order.
What is an MX record?
An MX (Mail Exchange) record is a DNS entry that tells other mail servers where to deliver email for your domain. Each record has a priority — lower numbers are tried first, and equal priorities share the load. If a domain has no MX record, it cannot receive mail.
Want to check how that mail is authenticated? Try the SPF Checker and DMARC Lookup.
