>Hello,
>I have a WC app that sends e-mail to users using wwipstuff. Now my customers require that these messages be digitally signed. Could somebody please point me in the right direction?

wwIPStuff doesn't support this. Digital signing is a very complex process that involves machine configuration and dealing with certificate stores. If you need to deal with this stuff using some very highlevel application like Outlook might be the easiest way to go...
