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" <marc@mandelswamp.com>
:
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
