Hello.

I need to configure the form to be sent by PHP SMTP from my server. How can I do it?

Thanks

You need a back-end script for that. You can use the scripts that CC Web Form Builder creates, here is how: https://www.coffeecup.com/help/articles … -designer/

You may also find online scripts that you can use.

Thanks for your answer but or is it necessary, Coffee Cup is prepared for that.

Here the solution:

Well, we might be speaking at cross purposes. Coffeecup has two apps for making forms: Form Designer and Web Form Builder. The former is for making a form pretty, the latter is for making the form work.
Since you posted your question in the Form Designer group, I thought that was the one you have, and since it has no back-end, I wanted to help you with that.
Apparently, you ought to have posted in the thread for the Form builder.

Anyway, good luck.
