Comment 2 for bug 215059

Can you try a %40 as the escape code for the @ symbol?

We do:

            user, host = netloc.split('@', 1)
            if ':' in user:
                user, password = user.split(':', 1)
                password = urllib.unquote(password)
            user = urllib.unquote(user)

So you should be able to do:

my%<email address hidden>
