MX Lookup Tool

Check your domain's MX (Mail Exchange) records to ensure proper email delivery.

What is an MX Lookup Tool?

An MX (Mail Exchange) lookup tool retrieves the MX records of a domain, showing which mail servers are responsible for receiving emails on behalf of that domain. MX records are essential for directing incoming emails to the correct mail servers.

How to Use the MX Lookup Tool

Enter the Domain: Input the domain name you want to check (e.g., example.com).
Click 'Check MX Record': The tool will query the DNS and fetch the MX records associated with the domain.
Review the Result:
- Priority: Lower values indicate higher priority mail servers.
- Mail Server: The hostname handling the email (e.g., aspmx.l.google.com).
- TTL (Time To Live): The time the record is cached before refreshing.

Frequently Asked Questions

1. What is an MX record?

An MX record is a DNS record specifying the mail servers responsible for receiving emails for a domain. It defines the delivery path for incoming emails.

2. Why are multiple MX records used?

Multiple MX records provide redundancy and load balancing. If the primary server is down, the email is routed to the next available server based on priority.

3. How do I add or update an MX record?

In your domain's DNS settings, add or modify MX records with the appropriate mail server and priority values. Example: 10 aspmx.l.google.com 20 alt1.aspmx.l.google.com
