We have 1 Mail Gateway Spam and Viruschecking Server in the DMZ and 1 Exchange Frontend Server and also one Exchange Backend Server.
Now we monitor the Mail Traffic over this Servers every 5 min. We have a Tool for this Process. This Tool send automatically a E-Mail to a ext. E-Mail Account. This Account replays the e-mail automatically to our Mail Server. Our Monitoring Tool checks if the E-mail is arrived or not.
