Let me add my 2 bits here. I am using PMB 1.25d and Java 1.1.8 with Gmail. If it is any help to anyone, I'll describe my setup.
Win2000, Stunnel 4.33, Java 1.1.8.
To set it up first install Stunnel in Win. Then create a shortcut to run Stunnel. Edit the shortcut and add "stunnel.conf" (no quotes) after stunnel.exe with a space inbetween. Replace contents of the sample stunnel.conf with the following:
-------------------------
client = yes
output = stunnel.log
# For Gmail email connections
[Gmail-pop3]
accept = 995
connect = pop.gmail.com:995
[Gmail-smtp]
accept = 465
connect = smtp.gmail.com:465
# End of config for Gmail
---------------------------
Drop the shortcut into your Startup Folder. You can manually start Stunnel now if you wish. No reboot necessary.
In PBM create a new incoming server as follows:
Mail host: localhost
Userid: (gmail email address)
Password: (gmail password)
Use SSL connection: UNCHECKED
Port:995
On your gmail account: setup POP access.
That should be all that is needed. Enjoy!
