This article is applicable for the users who setup the email services with Google Apps Mail
When the email service has been pointed to gSuite, you will not be able to use
our default SPF record as below:
"v=spf1 include:spf.mschosting.com -all"
If ever the SPF record was setup incorrectly, then you might receive the bounce back error message
from Gmail indicating on the SPF error where the IP is not allowed to send email from the domain.
In such, the default TXT record for Google Apps Mail need to setup as:
"v=spf1 include:_spf.google.com ~all"
