How to prevent certain file entensions from being used as attachments system wide
Is there an approach where we have the ability to not allow certain extensions as an attachment - system wide? I am aware we can do this via PeopleCode and also via URL objects with File Extension Lists, but those options are specific to certain attachments not all of them.
Is there some sort of setting to prevent all attachment functionality, system wide, for allowing/not allowing certain extension (i.e.. not allow ".js" or only allow "txt. doc, pdf")
