"sendmail"
Read the sendmail manual page... here are a few of the options: -Ffullname Set the full name of the sender. -fname Sets the name of the ``from'' person (i.e., the envelope sender of the mail). This address may also be used in the From: header if that header is missing during initial submission. The enve- lope sender address is used as the recipient for delivery status notifications and may also appear in a Return-Path: header. -f should only be used by ``trusted'' users (normally root, daemon, and network) or if the person you are trying to become is the same as the person you are. Otherwise, an X-Authentication- Warning header will be added to the message. Another usage could be: /usr/sbin/sendmail -t From: anyemail@address Subject: I am emailing myself Reply-To: anyemail@address To: anyemail@address This is an email to myself [EOF] It is exactly that easy to send an email from someone else (or from the person you are sending it to).
