Hi, I'm integrating an application (which uses Sendmail as MTA, and hybrid java/python mailing list manager) with apache jdkim.
Other existing oss libraries (which I'd previously based the app on) seem to work fine for plain text, but multipart/alternative results in DKIM result: fail (wrong body hash) I see there are no junit tests for content type multipart DKIM only for it's predecessor DK. In org.apache.james.jdkim.impl.Message on line 79 ((SingleBody) message.getBody()).getInputStream(); However RFC 4871, say that no special processing is required for multipart, so this cast might be valid. I'm debugging and would like to affirm the premiss that pache-jdkim-0.2 for multipart/* content types is indeed considered functional? when run on a multipart produces the exception (I added a try/catch - throwable): java.lang.ClassCastException: org.apache.james.mime4j.message.MultipartImpl cannot be cast to org.apache.james.mime4j.dom.SingleBody at org.apache.james.jdkim.impl.Message.getBodyInputStream(Message.java:80) at org.apache.james.jdkim.DKIMSigner.sign(DKIMSigner.java:85) I spoke to someone on the mailing list he seems to believe it does work, hash a bug been fixed in a post-release build, or has this uncaught exception been slipping through the net? Thanks. - Justin
