Why am I no longer receiving email notifications of form submissions?

I have stopped receiving emails when a customer has submitted a form.  How can I correct this?

Thanks.

Same.

Hello AcremeadKennels,

I checked your email address and found it in the bounce list. This was due Yahoo mail finding the sender addresses of your email notifications unauthenticated to be used such as those coming from Gmail and Hotmail but the IP address of the source of the email is from JotForm. To resolve this, please replace your email address sender to noreply@jotform.com rather than using their emails.

Reason(s) : smtp; 550-5.7.1 Unauthenticated email from ymail.com

I also have removed your email from the bounce list so it should try sending email alerts to your email address again. But please make sure to do the necessary changes or Yahoo will block the emails again.

Thanks.
