I recently configured S/MIME for email encryption. The encrypted emails sent was appearing as an attachment in receivers email box. After doing some R&D i found that it is Discliamer that is configured on Exchange 2007 which somehow interfered with Encrypted emails. I disbaled the disclaimer on exchange server and encrypted emails appeared fine in receivers mail box (Without attachments). Discliamer information is important to our organization and we cannot disable or delete it. Can someone advise if there is anything that can be done so that the Encrypted emails appear in receivers email box without attachments and without disclaimer being disabled or deleted.
