Just for everyone's knowledge, here is an email address I've found for SPF / Domain Keys / DKIM testing.
You simply send an email to: [email protected] It will then email you back and give you the report. Here is an example: This message is an automatic response from Port25's authentication verifier service at verifier.port25.com. The service allows email senders to perform a simple check of various sender authentication mechanisms. It is provided free of charge, in the hope that it is useful to the email community. While it is not officially supported, we welcome any feedback you may have at <[email protected] <http://mail.renshawauto.net/src/compose.php?send_to=verifier-feedback%40port25.com>>.
