I'm using Service Broker to [maybe] monitor my database events, so I have my activation sp in some user database and it should react on some events by sending e-mail to admin. But it fails with the error
The EXECUTE permission was denied on the object 'sp_send_dbmail', database 'msdb', schema 'dbo
while trying to use sp_send_dbmail.
How can I manage the permissions in my case?
