"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:
  1. Install Stunnel
  2. Install Stunnel configuration file for Gmail
  3. Install Stunnel as a service so it will start on every boot
  4. Configure Courier for Gmail through Stunnel
  5. Check Courier Properties
  6. Reboot or Run Stunnel
  7. Enable POP in Gmail

     b)  Click on Forwarding and POP/IMAP
     c)  Chose Enable POP for all mail   or   mail that arrives from now on
     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.
