===== Mail Tester Script =====

The script is based on zenity and the Postfix mail generator //smtp-source//. It is meant for testing mail-relays and what they return if something goes wrong. Or if you just need a lot of test mails send quickly.

There are a couple of more options available but I don't need them at the time. If you need them you can use this as a starting point and then just add them yourself.

	zenity --error  --text="Postfix Not Installed! \n\nTo install run 'sudo apt-get install postfix'"
	exit 0

# Ask for the host
