	If you want to send out voicemail notifications via Windows you'll need to change the mailer-app
	variable to the setting below:
	
	<param name="mailer-app" value="msmtp"/>
	
	Do not change mailer-app-args.
	You will also need to download a sendmail clone for Windows (msmtp). This version works without issue:
	http://msmtp.sourceforge.net/index.html. Download and copy the .exe to %winddir%\system32.
	You'll need to create a small config file for smtp credentials (host name, authentication, tls, etc.) in
	%USERPROFILE%\Application Data\ called "msmtprc.txt". Below is a sample copy of this file:
	
	###################################
	# The SMTP server of the provider.
	account provider
	host smtp.myisp.com
	from john@myisp.com
	auth login
	user johndoe
	password mypassword
	
	# Set a default account
	account default : provider
