Sign in to your domain hosting company's website using the username and password associated with your domain.

Navigate to an MX record maintenance page. MX records are special DNS (Domain Name Service) records, and are often located under sections titled "DNS Management," "Mail Server Configuration," or "Name Server Management." You may need to turn on advanced settings to allow editing of these MX records.

Delete any existing MX records before entering new MX records.

For each MX record, enter information according to the entries in the following table.

You may not be allowed to enter the priority values exactly as they appear in the table below; in that case, simply ensure that the server addresses are prioritized in the same order as they appear in the table. (i.e. The priority ranking [1, 3, 3, 5, 5, 5, 5] should work just as well as [1, 5, 5, 10, 10, 10, 10] so long as you keep the addresses in the right order.)

If you're asked to specify the type of each record you're adding, enter "MX".

MX records often require the specific format of DNS records, including a trailing dot (".") at the end of any full-qualified domain names (e.g. "server.example.com.")

Set any TTL values to the maximum allowed.

Change the SPF record to fight SPAM(optional)

You may define the SPF record to authorize only certain IP addresses to send email for your domain. This will prevent spammers from sending unauthorized email under a forged address from your domain.
