Sending anonymous emails from the Terminal
 

I read in a book a while ago how you can send anonymous emails without anything special like GREP | something i dont remember exactly... Can anyone help me with that ?

You can send emails with a changed sender (the 'From:' address), but the email is not anonymous. It can be tracked back to your machine by IP address. Even if your IP address changes, your ISP maintains a record of what IP address you used, so that you can be identified.

In your email client, hunt around the menus and you'll find an item like "view all message headers". You'll see the step by step record of the systems your email passed through. That record is kept by each server for a long time for law enforcement purposes.

In addition, sending email with a changed 'From:' address is usually against the terms of service for your ISP. In order words, your ISP can cancel your service - even charge you with spaming.

Does that answer your question?

Almost, i believe u misunderstood me i know that in headers there is going to be the ip; however, i meant to send an email simply without an email address like hackstacy@hell.com. To specify what email i want others to see and simply send it like that.

Ah, I think you are referring to a 'BCC:'. A BCC is a blind copy. The sender is disclosed, but the recipient list is not. If that's what you want, you can use the '-b' option on mail. For example:

In the above example, the email will be sent to user1@a.com and user2@b.net but the only 'To:' visible will be myemail@c.org.

Thats exactly what i was saying, but i seem to get this error "bash: mail: command not found"
when i do the last command. I guess i need a mail server or something.

You need to install mailx for your distribution.

I installed mailx and i dont get any emails to the email address i send and when the command mail gives me this :

You ISP is not accepting mail from 'hackstacy@ISMonitor'. You will need to specify a valid 'From:' email address that your ISP recognizes.
