Issue:

Select a "From" email address diferent than the introduced by the user in the html form.

How to solve:

The script generated by Forms To Go send an email to your destination address. Every email requires at least two email addresses: From and To.

In the past, if you didn't supply a From email address, there was no problem.

Nowdays, almost all email servers won't send email if the From is empty, because it's considered spam or virus.

What you have to do is select the Generic field, and write an email address that you like. Example:  This e-mail address is being protected from spambots. You need JavaScript enabled to view it

It's mandatory to have a "From" email address to guarantee that the email will be delivered and not considered as spam or invalid by the email servers.
