Νίκος ,
  You CLEARLY don't understand.  Please.  There are Mail headers and there are IP packet network headers.  They have to agree with each other or spam/malware alarms go off.  Even if you fake the mail headers, there is no way you can use fake IP packet headers, they are necessary for the underlying network hardware to work.
