Hi @leandroiwai,
No. The FROM header of an email has to be set to an address that the server sending the email is allowed to send from. For example, if your customer entered [email protected] and your server sent the email FROM that address, other email servers would reject is as spam because your server is not allowed to pretend to be gmail.com.
Instead, the plugin uses the REPLY-TO header to set the customer’s email address. Most email clients recognize this and use this email when replying. If your email client is not doing this, there may be a setting you can use to make it do so.
