Email feature not working

Email feature not working

We have recently installed the latest version of WebWork on our network, that was recently moved entirely to the cloud on AWS (Amazon Web Server) . Everything works fine except the email feature. Every time we try to use the "Email Instructor" button we get the error message:

Failed to send message: invalid hosts in Email::Sender::Transport::SMTP constructor at /usr/share/perl5/Email/Sender/Transport/ line 76.

Unfortunately our ITC staff are too busy with other pressing problems and my skills as Linux system admin are entirely negligible. I looked in the file site.conf  inside /opt/webwork/webwork2/conf and found the following line that seems to have been left blank:

$mail{smtpServer} = '';  # e.g. '' or 'localhost'

Is that where the problem might be?

Thanks for any pointers.
