[F] Mail Reply Address: Issue Resolved

[Dennis Tsang]

Ok try this:

In inc/mailhandlers/smtp.php, find: (at end of get_data method)

 return $string;

Before it, add:

  file_put_contents('./smtpmaillog.txt', $this->data, FILE_APPEND);

Try to send a mail again, and you should find a smtpmaillog.txt in your MyBB root folder. (You may want to pre-create this file, and CHMOD it 666 so that the server can write to it).
