In the email source, the DKIM-Signature seems to have an extra spaces

Code: 
DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=    mydomain.com; h=cc:from:reply-to:subject:subject:to; s=    myselector; bh=xxxxxx=; b=xxxxxx    xxxxxx    xxxxx=

this causes the DKIM validation to fail. Any idea what went wrong?
 
is there any other mail-processing on the way of this mail?
the signature-header PMG adds works in general - but something on the path might try to reflow the mail (which would invalidated the body-hash).
