"Google Gmail uses SSL (Secure Socket Layer) for my connection. Can Courier do this?
instructions contributed by RockFox of the Courier Beta Team
Courier does not have native SSL
support at this time. You can use an SSL tunnel program such as Stunnel, which is free.
These instructions have only been tested in Windows XP Pro SP2 and only
with Gmail. Internet Explorer 7.0 is the bowser.
To install Stunnel you need to know a few basic functions of running
Windows:
- How to be an Administrator (You must be an
administrator to accomplish this install)
- How to find a folder in which to save a file
I suggest that you read through the entire tutorial before you
begin to install. If you are not familiar with installing
software then you should view the Screen Shots indicated by
SS after each step
Experienced users should read the notes near the bottom..
There are 7 simple steps to setup Stunnel
(SSL) for Gmail:
- Install Stunnel
- Install Stunnel configuration file for
Gmail
- Install Stunnel as a service so it will
start on every boot
- Configure Courier for Gmail through Stunnel
- Check Courier Properties
- Reboot or Run Stunnel
- Enable POP in Gmail

d) Click on Save changes
Notes: The KISS (Keep It
Simple Stupid) method was used throughout the turorial with
the novice user in mind. Hence the install goes into the default
directory but you can use any directory you wish. However, the stunnel.conf file must be in the
same directory as stunnel.exe.
If you wish to save the sample
stunnel.conf do it right after step 1 as step 2 replaces it
with one specific to Gmail.
I used standard
ports for incoming and outgoing mail so that any anti-virus program
would not need to be changed..
There may be firewall issues. I use Commodo and I had to allow
Stunnel to access the Internet. I turned Commodo off and tried
the Windows firewall without difficulty.
I made no attempt to configure anti-spam program in this setup.
