Perhaps www.example.com *should* never be a sender domain ... but I have
seen many cases where a web server has a formmail [shudder] script that
calls a local sendmail directly. www's sendmail executable sends the mail
through another mail server (mx1.example.com or whatever), which then
delivers it to the destination mail server.
If the admin intended this formmail script to be used he would have
configured it to use proper channels and thus the correct sender domain. If
he did not do this, the use of the formmail seems to be unauthorized and if
the resulting mails are blocked by SPF this fine, IMHO.
