Resolve a DMARC error when using Google services

This guide is for owners of a domain name on the infrastructure who are having a DMARC issue when using certain Google tools like Meet or Calendar.

• Before: v=spf1 include:spf.infomaniak.ch -all
• After: v=spf1 include:spf.infomaniak.ch include:_spf.google.com -all

7. Click on the Save button:
