• 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.)
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.)
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.
stellarshores.com. IN MX 3 s7b1.psmtp.com.
stellarshores.com. IN MX 4 s7b2.psmtp.com.
Enter each of the MX records (as highlighted in the example above) in the “Mail
Server” column (this column may have a different name, depending on your
domain registrar). 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.
