Email Tenant Authentication Tools

With the changes to email domain authentication that Google, Yahoo, and Microsoft are rolling out I thought it would be prudent that I put together the tools you’ll need to check your email domain authentication. Along with the information on how to implement them. Below you’ll find three tools to check your SPF, DKIM, and DMARC DNS settings to make sure you don’t have any errors or missing records that will impact your email deliverability. Below are three tools you can use to check all of them.

Adding the records to your DNS

All three types are going to be TXT records for your DNS on your domain, but they all have some nuance to them. Each of them requires a different Host type when you’re putting them into the system. Below are examples I normally see, but check with your email providers documentation to be sure.

SPF Host is normally @

DKIM Host is usually [hostname]._domainkey

DMARC Host is usually _dmarc
