What MX records do
MX records tell other mail servers where to deliver messages addressed to your domain. Each record has a priority; lower numbers are tried first.
If MX records are missing, mail to your domain bounces — even when your website works perfectly.
Common problems
Records left behind after an email migration, MX entries pointing at a hostname with no A record, or a domain where MX was never configured at all.
