There are two ways: setting this globally for every form or setting it in the form settings.
Globally for all forms
Go to Quform → Settings on the WordPress admin navigation and go to the section Email sending settings. Select SMTP from the dropdown menu, you will be presented with a list of text fields where you can enter your SMTP server information. Every form will now use these settings by default. If you start getting an “Error submitting the form” your SMTP settings may be incorrect.
For a single form
In the Form Builder, go to Settings → Email → Email sending settings. Select SMTP from the dropdown menu, you will be presented with a list of text fields where you can enter your SMTP server information. Save the form and it will now send via your SMTP server. If you start getting an “Error submitting the form” your SMTP settings may be incorrect.
