@ghostsarespooky@infosec.exchange oh great! (derogatory)
Is there a way to add custom file extensions to an attachment block list? Or am I stuck using the list they provide me?

@Mustardfacial@infosec.exchange I don't think there's a way to add custom extensions, but a new attachement set definition in Policies -> Gateway Policies -> Attachment Management -> Set Attachment Management Policy -> Lookup -> Default attachment set -> New attachment set definition -> View -> View base extensions then drop the "50 v" drop list to as high as it will go. That should show -all- available extensions, but yeah, as far as adding custom ones, you're probably SOL.
