HELP Send Signed Message SMIME to a service

Did somebody already sent a signed mail to a webmethods service?
In the service, how can i grap the email sent to verify the signature.

Do I need a content handler?

From WMSample/smime, it create a smime message and then process-it but how actually from a Client smtp (outlook), we push the msg to a service ?

Thanks a lot
