Disable Request Validation

Questions
1

Hi :) , i am using umbraco v 4.7
i made a page to send emails , the point I used a free rich text editor for the mail body,

the point is everytime i try to send an email the following error occurs

A potentially dangerous Request.Form value was detected from the client (ctl00$ctl00$ctl00$ContentPlaceHolderDefault$cp_content$MailerControl_2$RtbBody="<p>bla bla bla<br...").

i checked the error  and all agreed that i must set

validateRequest="false"

http://www.asp.net/learn/whitepapers/request-validation
so when i go to the template and set


<%@ Master Language="C#" MasterPageFile="~/masterpages/umbMaster.master" AutoEventWireup="true"  validateRequest="false" %>

 gives the following error

Error parsing attribute 'validaterequest': Type 'System.Web.UI.MasterPage' does not have a public property named 'validaterequest'.

is there a solution for this :) ?

thanks
