Having problems with Autoresponder

I have run several test of form and recipients are not receiving an email comfirmation that their form has been submitted. I have set up autoresponder several times and no one is receiving the a response. Any Suggestions.

Hi,

In an attempt to stop fraudulent emails, Yahoo changed its DMARC authentication policy to reject emails that claim to come from yahoo.com but actually originate at non-Yahoo servers. So, do not use a yahoo user as your sender email address if you are to use Mandrill to setup JotForm email notifiers. Please read more about Yahoo and Mailchimp DMARC POLICY:

I would suggest either using a different custom sender address or using "noreply@jotform.com" as the sender address for your autoresponders.  Yahoo addresses may work but they are much more likely to bounce or be rejected.
