Now the problem is the line starting with "; from". This line is not a valid line in an email message 
header. Since it belongs to the preceding line it should start with some whitespace.

There are two possibilities:
a) Yahoo fails to add the Authentication-Results header in the correct format.
b) KMail corrupts the header when it receives the message.

I think b is highly unlikely because we would have noticed if there was such a serious bug in 
KMail. a, OTOH, is probably not noticed by many other people because other mail clients are 
probably more forgiving when they encounter such an invalid line in the header. You should be 
able to verify whether it's Yahoo's fault by checking your mail with another mail client and then 
looking at the source with this other mail client. Just make sure you do not check those 
messages with KMail because that might corrupt them.

Ingo
