PRTG Network Monitor is Paessler's powerful LAN and WAN monitoring software. The network utility checks the availability of network devices, tracks bandwidth usage, and gives you a complete overview of your network. PRTG's Email Round Trip Sensor allows you to monitor Exchange 2003 and 2007 availability and performance and ensure email end-to-end delivery.
PRTG Exchange Monitor checks whether your Exchange server delivers emails to the outside world, and whether email can be delivered to your email server. If you monitor Exchange, you can also see the time it takes for an email to be sent and delivered.
