Sender email

I have made updates to the sending email address field for my form in the advanced tab. I had the wrong SMTP login and want to edit it. How do i do that? I can't edit an email I've set up, from what I can tell. I tried adding a new sender email and entered the same email address and SMTP credentials except I used the correct login. However I wasn't prompted that I was going to overwrite the old one, and I have no way of checking what settings are in there for that email.

Also, is there lag between when I update by form and when the changes take effect? I have tried several different combinations of sender name and sender email address on my form and every email I get now just says Jotform in the sender name and noreply@jotform.com . I am getting frustrated at this and I can't seem to get the email set up back to the way it was.

The problem all stems from the fact that all of a sudden comcast no longer gets the email submission emails. They say the IPs are whitelisted and they are not filtering, but nothing is getting through.

I went on the forum for help, and any topic i select just opens a window and takes me to my form. 

To edit your SMTP settings on your form, please follow the instructions in this guide: How to Edit/Delete Sender Emails on SMTP Settings. You need to hover or if its not working click the email address and click "pencil" icon.
