----- Original message ------
Dear Andreas Stylianou:
In reply to your "Question on E-mail" (a copy of which appears at the end of my reply), if you mail client has the ability to show the full email header, then you often can tell if the name in the From: field is truly that of the sender. The fact that the two do not match may be due to how the individual's mail is processed rather than attempts to trick the receiver.
For example, I registered my own domain and currently use a commercial web hosting company so that my mail address can be independent of the ISP that I currently subscribe with. Therefore, in the header of my messages you will see:
From: "Marc E. Mandel" <[EMAIL PROTECTED]>
:
X-Sender: memandel/mail-hub.optonline.net...
The From field contains my mailing address and is the address that a reply will go to. However, mandelswamp.com only provides mail forwarding so my outbound messages must be sent to my mail account at my current ISP (Optimum Online).
If you wanted to send a message to someone and have him or her know for certain that you sent it, then you might consider encrypting or digitally signing the mail using Pretty Good Privacy (PGP) or Secure/Multipurpose Internet Mail Extensions (S/MIME) solutions.
Regards;
Marc Mandel

Dear all,
I believe that any one can change the From: field in its e-mail program and enter somebody else's e-mail address pretending that he/she is that person sending the e-mail.
Is there anyway that either the mail is not sent at all or the recipient knows that the e-mail received is not actually sent by the person whose name is stated in the from field.
Thank you
Andreas
