anyone use Mail Drop? i can't seem to get it working. i have the option selected in the mail preferences advanced tab. it tries to send the file normally, which crashes my mail, dumps it in Outbox..last test of it actually closed my iCloud access saying it used all my storage space so i wouldn't be able to send or receive emails until i bought more storage. I can't find any language that says it uses iCloud storage as a temp holding bin for mail drop items. either way, i have 3.5gb free in my iCloud storage and the file was smaller than that. not sure what i'm missing. thoughts?
