we're using Microsoft Dynamics CRM 4.0, Exchange 2007 and the email router, running on Windows Server 2008. The clients connect to the CRM server using both IE6 or IE7.
When sending emails the email body will be base64 encoded: Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: base64.
Is it possible to change the Content-Type to text/plain and the Content-Transfer-Encoding to for example quoted-printable? A base64 encoded email body triggers a lot of spam filters, and we want to avoid that.
Any pointers on how we can solve this issue are appreciated.
