I should connect to an smtp authenticated server, then use a specific mailbox to send emails, because the stmp server is authenticated ad a level domain.
According to my provider, credentials are:
- Server authsmtp.domain.com
- User: [email protected]
- Password: ***
$mail->IsSMTP(); $mail->SMTPAuth $mail->SMTPSecure $mail->Host $mail->Port $mail->Username $mail->Password
