I have recently seen a rash of SPF-related error messages in my courier logs related to SPF verification on 'ebay.com' domains:
Dec 5 05:11:12 colo courieresmtpd: error,relay=::ffff:66.135.209.218,from=<[EMAIL PROTECTED]>: 417 SPF error mx53.smf.ebay.com: Address does not pass the Sender Policy Framework
But when I submit this information to http://spftools.infinitepenguins.net, it reports that it passes SPF verification:

My courier configuration is set to only bounce on 'fail' or 'softfail', which I think is reasonable. And I know that I can just configure courier to not bounce on any SPF result code if this starts causing too many problems.
I'm just curious as to why courier's SPF checking says fail when others say pass.
Because you configured Courier to check the HELO domain address, in addition to the return address (probably).
The error message above shows that the address that fails the SPF check is 'mx53.smf.ebay.com'.
