I the the message headers are exactly the same. So I sent an email to
auth-results at to get a report.
It's the Canonicalized Bodies that are different.

When the test passes I get my  dns records back:

Canonicalized Body:

DNS record(s): 86121 IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDaf6SefY18HUDitRouHw9eP0zJ9W8BY2x+urENVAdmV/ghPjVnqjemJLBySGrXLiMiNO2Vs9js+3BVyblUZRj2CnK6uqUlkyWnJ9GUpZ8pfKZDP1s9gP0ASCDdsMzXEcNnPqyeko2jgbIn5eiZ6xeKwX/qV8JIQsTo/XzqWko7mwIDAQAB" 86121 IN TXT "o=~"

Public key used for verification: (1024 bits)

And when the the test fails I get the following back in the body:

Canonicalized Body:

At least I found where exactly it goes wrong, now to find where the problem comes from.

This message has been scanned for viruses and
dangerous content by MailScanner, and is
