That email address doesn’t work anymore. They changed it to check-auth@verifier.port25.com

You can find out more about it at http://www.port25.com/auth/

Another good site to use for testing is http://senderid.espcoalition.org/

Both of these addresses were working as of January 6, 2008.

auth-results@verifier.port23.com is not a valid address. Relevant portion of the bounce message below:

Reporting-MTA: dns;verifier.port25.com
Received-From-MTA:
Arrival-Date: Tue, 11 Dec 2007 09:46:34 -0500

Final-Recipient: rfc822;auth-results@verifier.port25.com

hi, auth-results@verifier.port25.com is exactly what I need. From some test sites, I know my SPF is right, but when send to one click I got “SPF lookup failed”, so I need a real test, I think auth-results@verifier.port25.com is right for that, but it seems auth-results@verifier.port25.com doesn’t exist anymore. Any idea?
