Is it possible to send an email showing it's from a different email?

[pneudralics]

I received an email from a teacher at a university with a .edu email address. By doing some googling the email is a scam email offering me millions.

 

Anyways so I was wondering if it's possible to send an email showing that it is sent from a different email address without knowing any login info on the email address you want to show in the email.

 

Example:

I send you an email from [email protected] but when you receive the email it can say [email protected] or something

 

I don't want to know how to do it. I just want to know if it's possible so I can reply back to the teacher and tell them to change their password or something.

It is.  With php:

 

<?php
mail('[email protected]', 'subject', 'message', 'From: [email protected]');
?>

 

[email protected] will receive from what appears to be [email protected].

Wait....  You actually believe emails like that?

 

 

 

Anyway, the emailing system is very trusting.  Too trusting in my opinion, but I must admit, I've never been able to think of a more reliable way of knowing who is whom.

Email was invented when only a few people used the internet. Everybody knew each other.

Reminds me of the first telephone clip from family guy. Youtube only seems to have the audio with some pictures of mario characters for some unknown reason:
