MX (Mail Exchange) records specify the mail servers responsible for accepting email messages for a domain. Lower priority values have higher precedence.
Ensure your mail servers are always reachable. Pinguzo monitors MX records, mail server availability, and alerts you on failures.
| 10 | Primary mail server (lowest value = highest priority) |
| 20 | Secondary mail server (backup) |
| 30 | Tertiary mail server (last resort) |
