Contact form not working correctly with @comcast emails

Hi, we have been using your contact form for almost a year without any problems.

However, our submission form is to forward the new signup each time a new volunteer used the form embedded on our volunteer page. Once they click submit, it is supposed to forward to 5 email addresses, but the 'comcast.net' email addresses are not receiving the form submission email

please let us know if there is an issue with comcast (we have an .edu address, a 'yahoo' address and two 'gmail' addresses that do receive the submission form)

thanks

Thank you for contacting us.

We have removed your Comcast email addresses from our bounce list. The email delivery attempts should be restored. However, we cannot guarantee that Comcast will not reject the messages for some reason and your email addresses will end up in our bounce list again. You may try whitelisting our sender email noreply@jotform.com on the Comcast side.

If you need any further assistance, please let us know.
