What is an MX Record?
An MX (Mail Exchange) record is a type of DNS record that specifies the mail servers responsible for receiving email for a domain. Each MX record contains a priority value and a mail server hostname.
Why Check MX Records?
1. Verify mail server configuration
2. Diagnose email sending/receiving issues
3. Check email system redundancy
How to Use the MX Record Lookup Tool?
1. Enter your domain name (e.g. example.com) in the input field
2. Click the "Lookup" button
3. The system will display all MX records including:
- Mail server addresses
- Priority (lower number = higher priority)
- TTL value (cache time)
- Response time
Important Notes
1. Ensure correct domain format
2. Check if multiple MX record priorities are properly set
3. Recommended to configure multiple MX records for redundancy
