When you are finished switching your MX records to the message security
service, go to “Test Your MX Records” on page 41.
Tips for Changing Your MX Records with GoDaddy
• If your domain registrar allows this, we recommend that you keep your current
MX records (examples shown in bold below) as a precaution 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 yourdomain.com.s7a1.psmtp.com
yourdomain.com. IN MX 2 yourdomain.com.s7a2.psmtp.com
yourdomain.com. IN MX 3 yourdomain.com.s7b1.psmtp.com
yourdomain.com. IN MX 4 yourdomain.com.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.)
• The default Time to Live (TTL) value for GoDaddy is 1 week. Therefore, if you
have not already changed this setting to a shorter length of time, you may
need to wait one week before your MX records are propagated. (Your email
will continue to flow during this transition.)
• Make sure each MX record is entered exactly as it appears below, including
the trailing dot at the end of each record. In this example, N equals your
system number for the message security service. (See your activation email
to make sure you are entering your correct system number. Be sure to enter
your actual domain name for yourdomain.com.)
For example, if your domain is stellarshores.com, and you are on System 7 for the
message security service, you would receive the following MX records in your
activation email:
stellarshores.com. IN MX 1 s7a1.psmtp.com.
stellarshores.com. IN MX 2 s7a2.psmtp.com.
