API to access Digital Signatures attached to the email

Hi All,

I wish to wirte an applicaiton which picks up emails from Outlook inbox and
then checks if the email is digitally signed. Then verifies the digital
signature and if found valid does some task.

I am trying to use the Microsoft Outlook 12.0 Object Library. But I don't
find any way to access the digital signature attached to the mail. The
Microsoft Office 12 Object Library has classes like SignatureInfo etc. But
I'm not aware of how to use these to read the digital signature attached to
the outlook email.

Regards, Gaurav
