Hello,
We would like to use SPAM protection in our environment. Our Sophos SG-210 accepts 3 email domains and redirect emails from these domains to a host which is an Exchange server.
Sometimes it happens that we do a maintenance on our Exchange server. During this time, I would like to suspend the delivery of our emails from the Sophos SG-210 to this Exchange server and I would like that emails stay in spool until our maintenance is finished.
Is there a way to do this? How can I set to stop delivery to Exchange server and spool the emails?
The only way I found so far is to close the network connectivity between our Sophos SG-210 and the Exchange server but I don't like this solution...
I tried with a firewall rule which I activate during the maintenance:
FROM: Any -> Protocols: Any -> To: Exchange server
But unfortunately the Sophos SG-210 is delivering mails. I guess that SMTP proxy is ahead firewall rules.
Can you help me?
Regards,
DeltaSM
