[stunnel-users] New and Utterly Confused on Ubuntu Linux

I am totally new to stunnel and am quite confused. I use Ubuntu 10.04 and
have installed the stunnel4 deb package. I need to do a couple of things. At
boot up I need to accept ssl connections on an inbound port and forward it
to a non-ssl compliant app listening on another port. The second thing I
need to do is make an ssl required connection to a pop server on another
host out of a non-ssl mail client on the local machine. I have no problem
with the ports, port forwarding, etc. I just do not know how to set up
stunnel to accomplish this.

Let's just use this as an example: 

1. I need to accept inbound ssl connections on 995 (port 995 is open) and
send them to the local machine non-ssl client listening on 2995.

2. I need to ssl connect to pop.gmail.com:995 via a non-ssl mail client on
the local machine and I want the mail client to connect to stunnel on port

3. I need both of these scenarios to start at boot up.

I don't even know where to start with stunnel4 to do this. Actually I can
set up stunnel.conf for either but one's a server operation and the other is
a client operation and can't get them both to work simultaneously. To start
stunnel at boot up I simply edited /etc/default/stunnel and
/etc/init.d/stunnel4 and changed ENABLED=0  to  ENABLED=1 in both files.
Something tells me this is entirely the wrong way to do what I want to do.
It works for either the client task or the server task, depending on which
one I have enabled in stunnel.conf but I just know this is not how I am
suppose to be doing it.

Will someone help?
