A few lines like this:
Message-ID: <[email protected]>
From: "<B3><AF><A6>B<AF>\" <[email protected]>
To: [email protected]
are in the headers of an email message sitting in my yahoo inbox. Is the last
quotation mark escaped? Is the message deliberately engineered in order to
fool mailers? As you saw, I'm fairly naive about these things.
