You can make the email to appear to come from any email<br/>example<br/>~HELO orgfree.com<br/>~mail from &lt;administrator@yahoo.com&gt;<br/>~rcpt to &lt;c14rock1710042@yahoo.com&gt;<br/>~data<br/>~ Hello,<br/>~ your account will be banned tommorow<br/>~ please save it by visiting this site <a rel="nofollow" href="http://carbon14.ueuo.com">http://carbon14.ueuo.com</a><br/>~ .<br/>~message sent!<br/><br/>it will appear to com from the administrator but the truth is it was from you<br/>
forgive my noobness. i'm assuming people know what email spoofing is. could someone explain what can be done once the spoofing is accomplished? :) cheers
You should lookup the MX record for the site your attempting to send mail to, A lot of domains use a separate host for their mail server. This can be done with nslookup or dig, There are also many web based tools to do DNS queries. Also you forgot to say HELO/EHLO before your mail from line.
