We have a web application that will allow users to use their own email address (domain name) to send emails. We are requesting their add the SPF record below, so that when our server sends an email using their domain name it checks and OK the email.
v=spf1 include:mail.bluedot-immigration.com ?all
1. Is this process correct ?
2. Is the SPF above correct ?
3. How can we check that the SPF record has been added to their domain DNS records ?
4. What to do if they don't have a personal domain name and use google or yahoo email ?
Help is appreciated.
