Dear All,
We have send one of our demo CSVB units to our customer for testing. After couple days of tests Spamblocker started dropping emails from outside email servers altough earlier everything wokred fine(emails from the same servers were delivered without problems).
Users that send the dropped email get in return message:
"Error 550 - To many invalid recipients".
At the same time, Spamblockers web interface stopped to respond. After reloading the device it works for abour 15 mins and then same story happens again.
Now emails are sent directly to server and spam blocker is disconnected.
Management interface is available, but we are afraid that after we will direct emails to the spam blocker it will drop it again.
I've tried to open a case with polish cisco small businness support, but it looks that spam blocker is after warranty and they can't help.
Is it possible that spam blocker doesn't work because license had expired?
This unit was delivered by our cisco sales manager to be used as demo unit at customers sites. Is there anything we can do about this unit or it needs replacement.
Best Regards,
Lukasz
