pop3 over stunnel


I am having difficulty setting this up.

Thunderbird connects, and just sits there saying connecting.
The logs show the connection but no data is transfered.

my configuration is;

cert = /etc/ssl/certs/stunnel.pem
sslVersion = all
exec = /usr/sbin/popa3d
execargs = popa3d
output = /var/log/stunnel.log
verify = 1
ciphers = HIGH
debug = 7

called from inetd
pop3s stream tcp nowait root /usr/bin/stunnel stunnel /etc/stunnel/pop.conf

output in the log is;

pop3 over stunnel

Hi all,

I upgraded stunnel to 4.5.3 - rebuilt the current package.
Now stunnel works fine. Must have been something with the version in 13.37

Don
