1. connected with "openssl s_client -connect mail.neroon.com:995", pasted cert to dreamhost.pem

2. used this -----------stunnel.conf------------- debug=7 client = yes

[pop3] accept = 110 connect = homie.mail.dreamhost.com:995 verify=1 CAfile=c:\temp\dreamhost.pem -----------stunnel.conf-------------

3. connect to localost:110, got "unable to get local issuer certificate
