Comment (by galbaras):

 Actually, the `-f` flag is only used when `!empty($this->Sender)`, which
 means that when there's no sender, the defaults should still work.
 Detecting the INI value and setting the Sender should resolve this
 problem, and in all other cases, things should behave as before.

 Either way, this forum isn't about phpMailer. It's about WordPress, and
 changes to phpMailer are outside the scope of the discussion. Feel free to
 suggest your change there.
