Send Email using service broker

Question

Hi,
i have a service broker application that i send message to the queue and a specific SP reads the message and process it, part of this processing is sending the information found on that message to a specific email accounts. this means i have two service broker applicatins, one for my business (sending messages to queue to be processed and the secound one is the SendEmail service)
when i send email using the SP "msdb.dbo.sp_send_dbmail" the email is recieved 100% true, but when i come to send the email through the SP which recieve the messages from the SB queue, the email is not sent and i dont know where it goes.
this means that i cant read from a queue and send to another one at the same time... can you help me in this!

Activated procedures execute under an EXECUTE AS context that prevents calls into anoter database (like msdb). See

This Solved my issue. 
My Error
The activated proc '[dbo].[usp_SB_Rcv_ApplicationError]' running on queue 'ServerDeadLockNotification.dbo.ApplicationError_Rcv_Q' output the following:  'The EXECUTE permission was denied on the object 'sp_send_dbmail', database 'msdb', schema 'dbo'.'
Code Causing the Error:
CREATE PROCEDURE dbo.usp_SB_Rcv_ApplicationErrorr
AS
BEGIN
SET NOCOUNT ON;
DECLARE @Handle UNIQUEIDENTIFIER;
DECLARE @MessageType SYSNAME;
DECLARE @Message XML
DECLARE @BodyTable NVARCHAR(MAX);
RECEIVE TOP (1) @Handle = conversation_handle,
@MessageType = message_type_name,
@Message = message_body
FROM [ApplicationError_Rcv_Q];
IF(@Handle IS NOT NULL AND @Message IS NOT NULL)
BEGIN
-- parse the message xml to get the error details
-- build the HTML table for send_dbmail
SET @BodyTable = (SELECT dbo.GetErrorEmailBody(@Message));
-- send the mail on the default profile
EXEC msdb.dbo.sp_send_dbmail
@recipients='[email protected]',
@subject = 'Errors',
@body = @BodyTable,
@body_format = 'HTML' ;
END CONVERSATION @Handle;
END
END
The Fix:
ALTER DATABASE [ServerDeadLockNotification]
SET TRUSTWORTHY
