Corgi, Thanks for a quick response. How do I find the account being used to actually send the mail? In sysmail_allitems a request has been made by a local account (NT Authority\System) and last modified by 'sa'. The SQL Server Agent has windows authentication selected in the connecting tab. I don't have access to the server itself, but I can get someone that does and get them to check what accounts are being used in the services.
