Hi Hamid_Khan, 

That's correct there is no date range when sorting by mail log - it displays all bounced/rejected emails regardless of date. You can always check your employee's email address by checking into their Employee Details and we would be happy to pass this request for a filter option as feedback. As mentioned above by my colleague, if the payslip has a Not Published status, this option was not selected when finalising the payrun and the payslips have not yet been sent to the employees. It would be best to check the employee's emails on file before trying again.
