I'm trying to do email spoofing in cmd in telnet but failed to do so.
I entered
C:\Documents and Settings\Owner>telnet alt3.gmail-smtp-in.l.google.com 25
Then it brought me here
220 mx.google.com ESMTP p59si7495147qga.25 - gsmtp
Typed this one
ehlo
Then it produced:
250-mx.google.com at your service, [122.54.217.133]
250-SIZE 35882577
250-8BITMIME
250-STARTTLS
250-ENHANCEDSTATUSCODES
250 CHUNKING
I continued typing this:
MAIL FROM:<cedrickapc@gmail.com>
502 5.5.1 Unrecognized command. s10si7413775qak.221 - gsmtp
Can someone please tell me why do I get error. Isn't it that Gmail is allowing outgoing mail relaying? And may I ask if I can use a disposable/temporary email provider such as dispostable.com for the recepient of this email?

It works fine for me, so I suspect there was an extra character in the MAIL FROM line confusing the parser.
