I'm trying to send an email through stunnel (which is running on the
mail server), but I keep getting an error.

My stunnel.conf is:
cert = /etc/postfix/smtpd.cert
key = /etc/postfix/smtpd.key
sslVersion = all
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
debug = 7
output = /var/log/stunnel.log
[ssmtp]
client = no
accept = 465
connect = 25
Does this mean that the SMTP proxy listening on port 25 is not
accepting the connection from stunnel?
Thanks,
James.
