I'm about at my wit's end with this one.
I have a Exchange FE Server connected to Mimesweeper Appliance. A SMTP Connector is configured to forward the mails to Mimesweeper Appliance which in turn forwards the mail to the Internet thru MEssagelabs.
Since past couple of days, we have had network problems. Which seems to have been resolved now.
A Notification Alert is configured to email when the SMTP Connector connection is lost. The SMTP Connector loses connection and has been sending an email exactly every 30 mins. After 10 mins it comes back online and can send emails again.
There are no errors in the Event Logs. I have enabled diagnostics for Exchange Transport and SMTP and set it to maximum. Even that doesnt provide any information.
Even Winroute doesnt give out much.
I know the SMTP Connectors are not configurable. But how does it generate an alert exactly after 30 mins and comes back exactly after 10 mins. Where r these setting stored.
The Mimsweeper box looks fine. Its able to communicate properly with the Frontend server. I have tested using telnet, response is good.
What could be the cause . Am I missing something here.. Really appreciate your help.
