Do you mean starttls*?

If so, use openssl:

   openssl s_client -starttls smtp -crlf -connect localhost:25 -quiet

Base64-encode the username and password.  With the openssl-wrapped 
connection, issue the ehlo of your choice and then:

auth login
<server will respond with 334 code>
Paste base64-encoded username here
<server will respond with 334 code>
Paste base64-encoded password here
<server should respond with 235 code>
