No I'm not some 1337 spammer, hell I dont even need it for spamming. Hence how my question has nothing to do with spamming. I'm not educated in this area clearly, calm down.
I started my reply with "is this a question or an answer".
the reply I gave was in case you posted an answer which I considered it inappropriate.
but since it was a question I apologize ;)
and to answer your question, to send spoofed emails you must use a open relay smtp (in case you are sending via smtp) or to configure sendmail to send spoofed headers (in case you are using php mail)
all my smtps are open relayed and yes, they can send spoof headers, so the receiver will get the email from anyone you want
