Try naming your object something other than objMail, also you might look into CDO.Message instead of CDONTS.NewMail.
Also, you can apparently have problems if some of the properties of the object are not set. Try this.
<%
Set objCDOMail=Server.CreateObject("CDONTS.NewMail")
objCDOMail.From=emailstring
objCDOMail.To="email@email.com"
objCDOMail.Subject="The Subject"
objCDOMail.Bcc="someemail@email.com"
objCDOMail.BodyFormat=0
objCDOMail.MailFormat=0
objCDOMail.Body=bodystring
objCDOMail.Importance=2
objCDOMail.Send
Set objCDOMail=Nothing
%>
