p.s. I notice that a cc: or to: to your email address bounces -- is that intended?

No, and AFAIK it's not happening to anybody else.

FWIW, here's the gist of the error message:

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

pje@telecommunity.com SMTP error from remote mail server after RCPT TO:: host mail.telecommunity.com [209.190.5.234]: 550 : Recipient address rejected: SPF Reports: SPF fail - not authorized

------ This is a copy of the message, including all the headers. ------

Return-path: Received: from oc.ex.ac.uk ([144.173.207.34]) by dot.ex.ac.uk with esmtp (Exim 4.62/mail) id 1HnLB1-0003Br-Sq; Sun, 13 May 2007 22:00:23 +0100

You're sending your message with a return address @gmx.net, but gmx.net's SPF records read: gmx.net. 300 IN TXT "v=spf1 ip4:213.165.64.0/23 -all" Which means that your ISP says that anybody using a return address @gmx.net who isn't sending their mail via the 213.165.64.0/23 IP block is a lying spammer pretending to have a gmx.net address. :) Thus, any SPF-supporting mail server is going to think you're a spammer and block your mail, unless you send it through a gmx.net-supported SMTP server.
