The odd thing is, there is no "to:" field in the widget - just "from" and "message". And yet the "undelivered messages" include random to:addresses.
I have Akismet set up, and I have tested that it works successfully (I get the spam failure message when I test with their test-spam-email address).
Clearly, something somewhere is being highjacked. Perhaps some sort of php mailer (don't know what contact form 7 uses - built in wp_mail?). How do I stop it?
I've contacted my host but they are unable to help me, other than to say "Disable Contact Form 7", which I don't want to do.
Email message below. The bottom bits were bits I added to my contact form in my WordPress installation, which is the only reason I figured out it was coming from my Contact Form 7 widget:
