Enfold forms not sending???

Hi, my site is no longer sending emails from the Enfold forms. I have contacted my host and they say it’s the site’s theme causing the issue. The email account/domain is using remote MX (Google). We contacted Google and they are saying the account must use the SMTP setting, yet with the forms on the Enfold theme, there is no way to set this. Any suggestions?

I’ve seen this code, but have not added is since I’m not sure it will solve the issue.

add_filter(‘avf_form_from’, ‘avf_form_from_mod’, 10, 3);
function avf_form_from_mod($from, $new_post, $form_params) {
$from = ” (Email address hidden if logged out) “;
return $from;
}
