Sending Mail via Telnet

Question

I Tried to send email via telnet. But it doesn't accept the data part. The following is the problem occured.

$ telnet 74.125.68.109 25
Trying 74.125.68.109...
Connected to 74.125.68.109.
Escape character is '^]'.
220 smtp.gmail.com ESMTP xr8sm26040278pab.26 - gsmtp

This mail is sent from telnet...
502 5.5.1 Unrecognized command. xr8sm26040278pab.26 - gsmtp

$

Here what is the problem after data command. Is there any mistake I did. 74.125.68.109 is the mail address of gmail.

It's telling you that you aren't saying HELO as your first command. After each line it's yelling at you again that you didn't say HELO
