I usually see that message when the SSL/TLS handshake failed in some 
way. Can you get a good connection to sendmail using openssl?

# openssh s_client -connect your.mail.host:25 -starttls smtp

Hmm. It'd be helpful to know your authentication chain:

1. The contents of /usr/lib/sasl2/Sendmail.conf

2. The contents of $MECH in /etc/sysconfig/saslauthd

Also, is saslauthd running?
