Tips for Changing Your MX Records for No-IP

If your domain registrar allows this, we recommend that you keep at least one
of 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
value of 10.
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

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.)
