Question fake email sender
Hi,

I am using the below command to send the email.

Code:
mailx -s  "test from `hostname`" email@gmail.com  < attachment.txt
id
uid=870(wlsuser) gid=641(wlsgrp)

I recieve the email as "From: wlsuser@hostname

Can I somehow have any string instead of wlsuser, if that grows too complex to achieve can i just have wlsuser and hide the @hostname that comes with it ?

Regards,

Try the -r return-address option. It still seems to include the domain though.
Code:
mailx -s  "test from `hostname`" -r "testing" email@address.com  < attachment.txt

P.S. You may want to edit out your e-mail address in the post so you don't start getting spam.

That works !!!

So now i have an email from testing@mycomputer

Can I somehow change the domain name if not hide it?

Depends, if you use a smart host, will the smart host accept the(from)email address.
If you don't use a smart host, not having a valid reverse dns for the domain you choose may cause the recipient to reject the email as spam.

Ok, however I am not sure what a smart host is and how it works.
Can you guide me on this ?
