Sending mail from another email-address

Lets see how we can send Email from another account.

The requirements will be a terminal only (surely with internet).

Use the following command.

mailx -r bob@example.com -s "The subject" adam@example.com
This goes inside the body of the mail
.................
.................
this is the end.

Now hit Ctrl + D.

That's it

Now Adam will receive an email from bob which is actually sent by you

Try it.
