• If the MX Record test fails for the selected domain, emails may not be filtered
or even bounce. You will see the results of the test followed by the relevant
parts of your DNS MX entries as seen by the DNS servers used by the
Message Security service. For example:
testmx to jumboinc.com: No MX record found containing
‘sla2.psmtp.com’
jumboinc.com IN MX 100 jumboinc.com.sla1.psmtp.com
jumboinc.com IN MX 200 jumboinc.com.sla2.psmtp.com
jumboinc.com IN MX 300 jumboinc.com.slb1.psmtp.com
jumboinc.com IN MX 400 jumboinc.com.slb2.psmtp.com
• For ‘No MX record found containing ‘sNaM.psmtp.com’’ or
‘No MX record found containing ‘sNbM.psmtp.com’’ -- Add the appropriate
entry. There should be one MX entry for each:
jumboinc.com IN MX 100 jumboinc.com.sNa1.psmtp.com
jumboinc.com IN MX 200 jumboinc.com.sNa2.psmtp.com
jumboinc.com IN MX 300 jumboinc.com.sNb1.psmtp.com
jumboinc.com IN MX 400 jumboinc.com.sNb2.psmtp.com
Additional Errors
