It used to be simple to add a script to just about anything in the computing world. Local vs cloud-based Android email apps typically lack any spam filtering. It seems trivial to allow the user to move undesirable email addresses to a Blacklist, then use a script to test incoming emails against that file & if found move them to the Spam folder rather than the Inbox. Anyone know if this can be done & if it's unusually difficult in the Android world? The app I have in mind is AquaMail. Thanks!
