[Hidden-tech] new spam call technique?

[Rich Roth]

Shel and others,
I need to clarify for all that forging an email address requires 
(almost) NO technical skill, unlike faking
a caller ID.  Doing that, at a minimum, requires interfacing with the 
phone system, although it seems easier
now that VOIP services are more common, at least it is actually illegal 
in many cases.

In contrast, forging an email address is so simple, because there is no 
verification of the from address
in the underlying SMTP (simple mail transfer protocol) used to send 
email, and available on
any internet connected system.  Any 'From address' validation you may 
see is done by the user program (MUA)
that you are running, not the transfer program (MTA).

For those interested, look up RFC 821 (dated Aug 1982) and subsequent 
IETF RFC's
