I try to send mail to one person.
It is OK
But when I try to send mail to 2 or more person.
It will show "Errno 2: mail(): SMTP server response: 553 5.1.3 <undisclosed-recipients:;>... List:; syntax illegal for recipient addresses at [ROOT]/includes/functions_messenger.php line 1799"
I checked about messenger.php line 1799, it is wroten
$result = mail($to, mail_encode($subject, ''), wordwrap(utf8_wordwrap($msg), 997, "\n", true), $headers, $additional_parameters);
Does anybody know how to solve it ??
My system is phpbb3 3.2.2 and window 10 pro.
Thank you for your answer
