Hi,

Im trying to bind my 465 port tu my 25 port to have a ssl-smtp with the following command:
stunnel -p /etc/stunnel.pem2 -d 465 -r localhost:25
However when I try to connect to port 465, I get the following error,
stunnel[3443]: SSL_accept: Peer suddenly disconnected
Any idea? Thank you
Eric

I've got that system working on an OLD Linux system here.... 

In my case, I added it as a line to my  /etc/inittab, so I'm running it in the "foreground" since init will respawn it if it ever dies.  Here's my invocation:

stunnel -d 465 -r smtp -f -n smtp -p /usr/share/ssl/certs/sendmail.pem

I think the part that you are really missing is the   -n smtp   switch setting.
