We are using Exchange 2007 and are interested in Paessler network monitor. We have a Send Connector to our smarthost configured under hub transport. It is configured to send email to our Barracuda Spam and virus Firewall for outbound processing. I would like to know if there is a sensor to monitor this so that if the send connector stops relaying messages to the Barracuda, I will be alerted. Has anyone seen a sensor like this? can one be created? Sorry I am very new to network monitoring.
Thanks in advance.
