IMPORTANT: Your activation email may display a set of four MX records as
shown below. 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.
However, if DreamHost allows you to enter only one MX record (as described in
the example above), enter only the one MX record with the highest priority (lowest
number, for example “MX 1”) from your activation email.
When you are finished switching your MX records to the message security
service, go to “Test Your MX Records” on page 41.
