I am using multiple mail services for my domain sliver.proteuslake.asia, such as Mailjet, Google, and Atlassian. I have already added three TXT records for my domain:
"v=spf1 include:spf.mailjet.com ?all"
These records are used for different purposes, such as verifying my domain ownership and allowing Mailjet to send emails on my behalf.
I want to add another TXT record for a different purpose, but I am not sure if it will affect the SPF authentication method. SPF is an email authentication method that uses the DNS to authorize which IPs can send mail on behalf of my domain. The receiving mail server checks the SPF record of the sender's domain to verify that the sender's IP address is authorized.
Will adding another TXT record impact the SPF authentication method? If yes, how can I avoid it? If no, why not?
