Failure using SQLMapi, check SQL Server error log.
The sp_processmail stored procedure failed to perform one of its mail functions.
If the SQL Server error log contains errors 17903 and 17951, resolve those errors first and then run the sp_processmail stored procedure again. If errors 17903 and 17951 do not appear in the error log, close and restart the client application and run the sp_processmail stored procedure again.
If error 15080 occurs again, call your primary support provider for assistance.
