But I'm not that familiar with SPF to tell something about why it failed (scored +1.4pt due to SPF softfail). Even with that SPF failure the mail wouldn't have been blocked when it was a normal email with a normal timestamp ;-) Yes, it influences only the score, of course.

It's suggested to use it only for "scoring" - using spf directly for blocking or other purposes will result in very very much false-positives. using spf records to detect spam is another thematic.

I also didn't mention the messages about the SPF record set of the sender domain, because I'm not familiar enough with SPF.

We had something similar with a php script we wrote for our contact-form. When we used \r\n in the headers, the mail was detected as spam. When we used only \n everything was okay. "Note: If messages are not received, try using a LF (\n) only. Some poor quality Unix mail transfer agents replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with » RFC 2822." Another thing, thats what you've seen, are charset problems. for example if using php with utf-8 and using an iso-8859-15 sending script and vice-versa.. i don't know why great companies like ebay don't fix their mail systems, but i know ebay is not the only one doing such things.
