Reports need validation on Email Delivery fields
See attached image. When trying to send reports via the Email Delivery tab, the emails do not get sent if invalid characters are included in either the To or the CC fields. In our case, the user included extraneous spaces and commas, as shown in the diagram. No warning is given to the user in this instance, which leads to confusion when the emails don't get sent, and a system administrator needs to examine errors on the back end to determine the problem and correct it. It would be much preferable for appropriate validation to occur on these fields to prevent invalid values from being entered in the first place, with messages being displayed towards the user entering the invalid values.
