"Charge the sender" was discussed yesterday at the famous 'spam summit' at
the house of commons in
the UK. View seems to be: this will further encourage the practice of
spammers to gain control of
legitimate email servers, with the intention of sending out spam from an
'authorised' sender (the
recent piece on the BBC re British Airways as a source of spam refers..).
This idea will NOT work
in practice. Naive innocents would pick up the charge.
