Fix Asterisk email message notification problem.

We switched hosting providers last week for our bespoke/custom Asterisk installation and received a new IP address, etc., etc.. Now, our email message notification is not working and we think it is related. Our pre-existing technical help seems out-of-the-loop with all the events in the Ukraine. More work is available to upgrade the installation and will be needed after email problem is solved. Only experienced Asterisk techs should apply.
