Additional comments

The cause

In file libraries/src/Mail/MailerFactory.php, line 83

 if ($mailer->setFrom($mailfrom, MailHelper::cleanLine($fromname), false) === false) {

needs to be changed to

 if ($mailer->setFrom($mailfrom, MailHelper::cleanLine($fromname), true) === false) {

The php "mail" needs $additional_params = "-fsupport@mydomain.com"

mail(
    string $to,
    string $subject,
    string $message,
    array|string $additional_headers = [],
    string $additional_params = ""
): bool
