Hi Michael,
it's not so simple. I test this internally, so only one MTA(postfix)  
is involved.
I'm also not sure, that this header is the reason for the verification  
failure.
However, if it is added by the MTA, shouldn't it be added by IMP  
before signing?
I've attached 3 complete Messages.
mail-1 contains only the letter 'a' (and my signature) and can be verified.
mail-2 contains only the letter 'ä' (and my signature) and cannot be verified.
mail-3 is what imp appended to my Sent-folder(when sending mail-2),  
this one can be verified.
