wp mail – How Can I Change Default Reply ToEmail

I want to set the SMTP settings manually instead of using a plugin. I did this using this resource. However, there is a problem.
If the user clicks “Reply”, a different e-mail appears. Probably I’ve described this before with the plugin. However, I cannot remove it. If I make a new definition as below, it creates a new reply e-mail. Therefore, the past is not erased.
What I want: If the user clicks to reply to the incoming e-mail, only smtp_from e-mail should appear.

My Codes:


define ('SMTP_FROM', 'example@example.com');


add_action ('phpmailer_init', 'my_phpmailer_example');
function my_phpmailer_example ($ phpmailer) {
$phpmailer-> From = SMTP_FROM;

//$phpmailer->addReplyTo('example@example.com ',' Information ');
