SMTP error while using PHP mail()

[the-djmaze]

SnappyMail is still trying to use SMTP despite being set to use PHPmail. This is returning a fun combination of errors relating to the fact that the SMTP host input is empty and no error handling exists for such a contingency.
I was able to trace back the error to /snappymail/v/2.25.0/app/libraries/RainLoop/Actions/Messages.php at approx line 862, its odd that the error traces back to a private function smtpSendMessage when I don't have SMTP enabled. Furthermore since I did not supply a SMTP host the error handler even managed to bug out causing layers of errors in the log.

This fix seems to work.
