Hello All, A quick question regarding the stunnel ability to work with the following scenario. Scenario is: I have an Exchange Server sitting on the external perimeter with Outlook Web Access (OWA) enabled and it is the frontend and backend mail server as well. And I have a remote client which has a Thunderbird Client (for example) that I need it to connect to the Exchange Server to retrieve emails. The only inbound port to the Exchange Server from a network perspective is HTTPS-443 and no other ports are open on the firewall. Now the question is how can a client thunderbird connect to the Exchange Server/OWA with only 443 port open. So what i was thinking is and tell me if this works? If i install two instances of STUNNEL one on the remote client and one on the exchange server and the following happens. on the client the stunnel listens on port 25 SMTP and encrypts and forwards to port 443 then the server recieves and listens on port 443 and decrypts and forwards to port 110 POP3 will that work actually? hmmm i wish i explained that pretty well. if not then how can it work with the given scenario. cheerz.
