Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

What is the version of openssl installed in your box? Because this bug is from 2005, so I guess there should be already fixed.
Anyway you might use your package manager to upgrade openssl version if possible, or d/l the srpm, patch and install. Dunno how it's done because I don't use an rpm based distro
haven't used gnutls-cli, i might be using the command wrong but when I try something like:
gnutls-cli --crlf --starttls
-bash: gnutls-cli: command not found
I can see it's installed in my rpm:
Package gnutls-1.4.1-3.el5_4.8.x86_64 already installed and latest version
When I try: /usr/local/ssl/bin/openssl s_client -starttls smtp -connect localhost:25
still seem to be getting the same error, and some additional ones but I think its they way I have the location of my certs setup in config:
47923882121184:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:683:
no peer certificate available
No client certificate CA names sent
SSL handshake has read 298 bytes and written 245 bytes
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
After turning that extra debug on saw that there was problems loading the auth_key. Once I unencrypted the key was able to get the correct output from: openssl s_client -starttls smtp -connect localhost:25
But when I try sending email to host that require user verification getting this in the maillog:
to=<firstname.lastname@example.org>, relay=syndicate-gaming.com[22.214.171.124]:25, delay=0.4, delays=0.02/0.01/0.29/0.08, dsn=5.0.0, status=bounced (host syndicate-gaming.com[126.96.36.199] said: 550-Verification failed for <email@example.com> 550-No Such User Here 550 Sender verify failed (in reply to RCPT TO command))
