I use Pan to access my easynews account. To get an encrypted connection I use Stunnel.
This is my configuration:
client=yes
verify=0
foreground=yes
pid=
syslog=no
[easynews]
accept=2119
connect=secure.news.eu.easynews.com:563
TIMEOUTclose=0
TIMEOUTidle=600
Then it is just a matter of configuring Pan to connect to 127.0.0.1 on port 2119.
