Yahoo mail not to be used for your account setup

Recently Yahoo mail domains have implemented additional protocols when using their domain name to send email. They started to embrace DMARC more explicitly.

This is because Yahoo will no longer be accepting messages where the From domain is a Yahoo mail domain, as used in your GroupQuality account email address. This is a security measure they have implemented to help reduce potential address spoofing of their mail domains.

What this means: You can no longer send with the From address being anything from a Yahoo address in your GroupQuality account.

What you can do: You will need to change your account email address to a non-Yahoo email address. First and foremost we recommend using your own mail domain such as john@mycompany.com, or one you control other than yahoo mail.
