Want a computer you can telnet into and mess around with, and not get into trouble no matter what you do to it? I've set up mytechbroker.com (188.8.131.52) with user xyz, password guest for you to play with. Here's how to forge email to firstname.lastname@example.org usingtelnet. Start with the command:
C:\>telnet techbroker.com 25Connecting To Techbroker.com
Now you type in who you want the message to appear to come from:
helo email@example.comTechbroker.com will answer:
Next type in your mail from address:
250 Requested mail action okay, completed
Your next command:
rcpt to:firstname.lastname@example.org Requested mail action okay, completed
Your next command:data354 Start main input; end with
Anyhow, try typing:
This is a test..250 Requested mail action okay, completedquit221
Connection to host lost.
Using techbroker's mail server, even if you enable full headers, themessage we just composed looks like:
Status: RX-status: N
This is a test.
That's a pretty pathetic forged email, huh? No "from", no date.However, you can make your headers better by using a trick with the data command. After you give it, you can insert as many headers as you choose. The trick is easier to show than explain:
Connection to host lost.
The message then looks like:
from:email@example.comDate: Mon, 21 Oct 2002 10:09:16 -0500Subject: RudolfThis is a Santa test.
The trick is to start each line you want in the headers with one wordfollowed by a colon, and the a line followed by "return". As soon asyou write a line that doesn't begin this way, the rest of what youtype goes into the body of the email.
Notice that the firstname.lastname@example.org from the "mail from:" command didn't show up in the header. Some mail servers would show both "from" addresses.
You can forge email on techbroker.com within one strict limitation.Your email has to go to someone at techbroker.com. If you can find any way to send email to someone outside techbroker, let us know, because you will have broken our security, muhahaha! Don't worry, you have my permission.
Next, you can read the email you forge on techbroker.com via telnet:
C:\>telnet techbroker.com 110
+OK <email@example.com> service ready
Give this command:user xyz+OK user is known
Then type in this:pass test+OK mail drop has 2 message(s)
retr 1+OK message followsThis is a test.
If you want to know all possible commands, give this command:
help+OK help list followsUSER userPASS passwordSTATLIST [message]RETR messageDELE messageNOOPRSETQUITAPOP user md5TOP message linesUIDL [message]HELP
Unless you use a weird online provider like AOL, you can use thesesame tricks to send and receive your own email. Or you can forge email to a friend by telnetting to his or her online provider's emailsending computer(s).
