Last night,
I have applied the latest Firmware and all went good....for a while.
Now Sophos Endpoint are not able to update and Imap/s is not working. I have tried to re-apply the previous firmware v16.05 but no changes.
If I reboot the appliance, Imap for few seconds reconnect back to mail servers.
I was able to make the Sophos Update working by creating a top rule Lan --> Wan with any service. IMAP does not work at all even with this rule.
Of course removing the XG, everything works perfectly.
Possible bug?
