Change Your MX Records 31
Make sure each MX record is entered exactly as it appears below, including the
trailing dot at the end of each record. Be sure to enter your actual domain name
for yourdomain.com. 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.)

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.
stellarshores.com. IN MX 3 s7b1.psmtp.com.
stellarshores.com. IN MX 4 s7b2.psmtp.com.
Enter each of the MX records in the “Record Value” column. Be sure to enter your
actual domain name for yourdomain.com. Be sure to include the trailing dot as
shown in this example, and assign priority values of 1, 2, 3, and 4:
When you are finished switching your MX records to the message security
service, go to “Test Your MX Records” on page 41.
