Our application is not able to establish SSL connection with POP3 server due to some restrictions. Hence we thought of using stunnel for the same.

Now we have installed stunnel in out application server.

In the config,

connect = POP3_address:port

accept = ??

What should be the value for 'accept' parameter should it be the IP of our server? 

Our server works in the same way as Outlook client, using the POP3 details, connect to the server and retrieve the emails. So what needs to be done in POP3 details, so that it connects via stunnel?

Any other parameters we need to change in stunnel.conf file for accessing POP3 server via stunnel?

Thanks in advance!!
