Email Auto Responder — Whose STMP username & password do I use?

I'm setting up an email auto responder for my Client. Based on the help page example @ How-to-Setup-SMTP-for-a-Form , I'm not clear whose Username and Password information should be used?  The Client's custom domain login credentials or my JotForm account?

Thanks,
Arleen

Hi,

   You would set this up based on the account you would like the auto-response to come from.  In this case, if you would like it to come from the client, you would need to set things up based on their credentials.  This would allow the auto response to originate from their email rather than the default Jotform one.  If this does not resolve your issue please let us know and we will be happy to help.

Thank you for using Jotform!

Thanks David.  I suspected this was the answer but wanted to make sure before approaching my Client for his private information.

One follow up question: Am I correct in understand the email server's IP address will be that of my Client's web host not JotForm's?  I ask because I have a free JotForm account and I want to make sure to circumvent DMARC validation.

Yes, it must be from your web host/email service provider. When you create SMTP, all credentials must be from your email service provider since you're using your email provider's SMTP to send emails.

Should you have further questions regarding this matter, let us know here.
