we are running sophos puremessage on a 2008 r2 std server which then relays on to an exchange 2007 server.
we have been informed that an external vendor is trying to send encrypted emails to one of the users on site but we are finding that the emails are not getting passed puremessage eventhough encrypted emails has been allowed. We think this is coming down to TLS not enabled on the server.
we have tried telneting to the puremessage server and running the ehlo cmd which should show TLS starting but it doesnt. When i go into IIS6 which is required for puremessage there is no option to install a certificate and we just get the message 'TLS is not available without a certificate' i have checked the local server and it has a selfsigned certificate but i am stuck from here.
any assistance would be appreciated
