[dev] S/Mime signature not validating (Was Fwd: Test)

Resending this since I forgot to change the subject from "Test":

While testing and looking at the code for s/mime support in  
ActiveSync, I've discovered that the following email, sent from iOS  
validates fine on the iPhone and in Apple Mail, but Horde says the  
signer's certificate cannot be verified. It is signed with the same  
certificate that I sign all my Horde email with - and this verifies  
fine when the original email is sent from IMP.

I see some minor differences in values of some of the headers, but  
can't figure out what the issue is. IMP shows the following structure  
when viewing All Parts in the preview pane:

Signed
|
|- Text
|- smine.p7s


an email sent from IMP shows the following structure:

Signed
|
|- Text
|- S/MIME Signature


Any ideas where to look to further figure out why these are not  
validating in IMP?
