Tips for Changing Your MX Records for DNS Park

If your domain registrar allows this, we recommend that you keep your current
MX records (examples shown in bold below) as a precaution for 48 to 72
hours, or until you have verified mail flow through the message security
service. However, be sure to assign the MX records shown in your activation
email with the higher priority values (lower numbers).
For example, the values of 1, 2, 3, and 4 represent higher priorities than the
values of 10 and 20.
yourdomain.com. IN MX 1 s7a1.psmtp.com
yourdomain.com. IN MX 2 s7a2.psmtp.com
yourdomain.com. IN MX 3 s7b1.psmtp.com
yourdomain.com. IN MX 4 s7b2.psmtp.com
yourdomain.com. IN MX 10 yourmailhost1.yourdomain.com
yourdomain.com. IN MX 20 yourmailhost2.yourdomain.com

Once you are sure that mail flow through the message security service has
been established, we highly recommend that you remove your old MX records
to ensure your email traffic does not bypass the message security service and
connect directly to your mail server. (You verify your MX records later in the
activation process. See “Test Your MX Records” on page 41 and “Test Filtered
Mail Flow” on page 45.)
