Generally you wouldn't logon to an SMTP server (unless authentication is
required).
For a typical SMTP session It should be something like the following (each
line is a new command followed by return).

telnet
open mail.server.com 25
helo a
mail from: email@xxxxxxxxxxx
rcpt to: recipaints@xxxxxxxxxxxxx
data
body text goes here.
..
quit

If your going to use pop3 to check your email then it would be more like
this

telnet
open mail.server 110
user usernamegoeshere
pass passwordhere
list
retr n (to retrieve the message where n is the message number)
dele n (delete a message by the list number)
quit

(if you don't quit out changes will be lost)
