Hi Our overdue notices are not being sent to patrons. They show in the patron's Notices tab with a failed status. When I look in the message_queue table, the to_address field is 'NULL'. Can anyone suggest why this is happening. The patron does have an email address. We are using version 3.02.00.004.
