Hi Stefano, I was very happy to discover that you where signing millions of email's initially, now I'm just confused. This is an uncaught exception, so I was thinking maybe it was unnoticed or something.
I'm using apache-mime4j-0.7.2, apache-jdkim-0.2 lists this as a dependancy in the maven pom.xml. DKIMSign.pl is written in perl, if this is what you are referring to. I am not a perl developer and can barely read perl. But I'm open to any solution at this stage, I did see there is a test class called org.apache.james.jdkim.PerlDKIMTest, how does perl relate to the apache-jdkim project? I've had a look at the causes for the ClassCastException, and it is not easy to fix, due to inheritance issues. These two classes have completely different abstract parent classes, they can only be referenced by org.apache.james.mime4j.dom.Message because their concrete children implement the interface. Are you suggesting I revert to apache-mime4j-0.7 rather then apache-mime4j-0.7.2?
