Hi Davide,

just a newbie question regarding the SMTP standard:

I wonder why besides "MAIL FROM:" and "RCPT TO:",
there are also these fields in the mail header:
 "From:", "To:" (and optionally "CC:" and "BCC:")

When do these fields do differ from each other?
I mean what's the difference between "MAIL FROM:" and "From:",
and the difference between "RCPT TO:" and "To:" ?

Recently I received a spam mail which was in the "To:" field
adressed to someone else at an other domain, but it was delivered
to me because in "RCPT TO:" my email adress was specified.

Is this case a bug of xmail or is it one of the shortcomings
of the SMTP standard?


TIA
