You need to understand SMTP.  You can look at RFC821 here:
http://www.faqs.org/rfcs/rfc821.html

Here is a dialogue which does what you want:

csh> telnet mail.tic.com 25
Trying 68.14.224.76...
Connected to ns1.tic.com.
Escape character is '^]'.
220 ns1.tic.com ESMTP Sendmail 8.14.1/8.14.1/Debian-8ubuntu1; Fri, 28
