Hi!

The paypal.de Mail verified in Mail::DKIM because it contained a valid
DomainKeys Sig, too. The DKIM sig is broken.

Nevertheless I found a bug in the DKIM implementation of exim, too.
http://bugs.exim.org/show_bug.cgi?id=1067

Headerlines with trailing white space characters are handled wrong and
break signature verification for "relaxed headers" messages.

Regards, Wolfgang
