MX Lookup Tool

An MX Lookup Tool helps you find the Mail Exchange (MX) records of a domain. These records indicate which mail servers are responsible for receiving emails for that domain.

Using the MX Lookup Tool ensures that your domain's email routing is correctly set up, preventing issues with email delivery. It's especially useful for troubleshooting email-related problems.

The tool displays the mail servers associated with a domain, including their priority, hostname, IP address, and TTL (Time to Live).

If emails aren't being delivered, checking your MX records can help identify if they're misconfigured or pointing to an incorrect server.

Yes, our MX Lookup Tool is entirely free and available online without any usage limitations.

It's a good practice to check your MX records periodically or whenever you make changes to your domain's DNS settings.

The MX Lookup Tool provides real-time data based on current DNS records. However, the accuracy depends on the freshness of the DNS information and global DNS propagation.

No, the tool currently supports one domain lookup at a time. You can use it multiple times to check different domains.

If you encounter outdated or incorrect information, ensure the DNS records have been updated and try clearing your DNS cache. You may also want to verify the results using other MX lookup tools.

Priority values indicate the order in which mail servers are used. Lower numbers represent higher priority. The mail server with the lowest priority number is tried first.

There is no limit to how many times you can use the MX Lookup Tool. You can perform multiple lookups as needed.

An MX (Mail Exchange) record is a DNS record that specifies the mail server responsible for receiving email messages on behalf of a domain. When an email is sent to a domain, the sending server queries the MX records to determine where to deliver the email.

Yes, a domain can have multiple MX records with different priorities. This setup provides redundancy and ensures that if one mail server is unavailable, the email can be routed to another server.

If no MX records are found for a domain, the email cannot be delivered, and the sending server will typically generate an error message. different priorities, which provides redundancy in case the primary mail server is unavailable.

A backup MX record provides a fallback option if the primary mail server is unavailable. It has a lower priority (higher number) and ensures that email delivery continues even if the primary server fails.

The priority in an MX record determines the order in which mail servers are used. Lower numbers indicate higher priority. The server with the lowest priority is used first, and if it fails, the next in line is tried.

TTL (Time to Live) is the duration for which the MX record is cached by DNS resolvers. After the TTL expires, the DNS resolver queries for the updated record.

No, MX records point to a domain name, which in turn should have an A (IPv4) or AAAA (IPv6) record that points to an IP address.

No, MX records should not point to a CNAME (Canonical Name) record. Instead, they must point to a domain name with a corresponding A or AAAA record.

You can update your MX records through your domain registrar's DNS management interface. It usually involves specifying the new mail server's hostname and setting the priority.

Changes to MX records typically take 24 to 48 hours to fully propagate across the internet, depending on the TTL (Time to Live) setting and the global DNS cache.

Common issues with MX records include misconfiguration, incorrect priorities, and DNS propagation delays.
To troubleshoot:

1. Check Configuration: Ensure MX records point to valid domain names with correct priorities and that these domains have valid A or AAAA records.
2. Verify Propagation: Use our online MX Checker tool to check if MX records have propagated globally. It can take 24-48 hours.
3. Review Logs: Check mail server logs for errors related to MX record resolution.
4. DNS Cache: Clear your DNS cache or try accessing from different networks to rule out local caching issues.
5. Check for Conflicts: Ensure no conflicting DNS records, such as multiple MX records with the same priority or CNAME records where A records should be.
