Does this example do what you need?

testing:~> mail -v dwerken   <=== this is the command
Subject: Hey
Testing                       <=== NOTE:  I hit CTRL-D to exit from the text entry mode.
  <= dwerken@testing U=dwerken P=local S=314
testing:~> Exim version 3.35 debug level 1 uid=8 gid=8
Berkeley DB: Sleepycat Software: Berkeley DB 2.7.7: (08/20/99)
delivering message 1CTkVN-0005kC-00
  => dwerken <dwerken@testing> D=localuser T=local_delivery

After you send the mail, you'd type "mail" at the prompt to see if you got it:

testing:~> mail
Mail version 8.1.2 01/15/2001.  Type ? for help.
"/var/mail/dwerken": 1 message 1 new
>N  1 dwerken@testing    Mon Nov 15 12:19   14/421   Hey

Try this generic procedure for testing SMTP (>> is stuff you type, << is stuff you get back):

$ telnet 25 (or telnet yourhost:25 on some systems)

<< 220 blah blah
>> HELO yourclientname
<< 250 Hello [ip address]
>> mail
<< 250 2.1.0 ...Sender OK
>> rcpt
<< 250 2.1.5
>> data
<< 354 Please start mail input.
>> Subject: Test message
>> This is a test...
>> Testing 1-2-3
>> .
(note, ^^^^  that is a period on an otherwise blank line to end)
<< 250 Mail queued for delivery.
>> quit

This was tested on Exchange, but it should work for any other SMTP server.  Please don't make any typos, since backspace usually doesn't work as expected.

I hope this helps.
