curl -n -o ~/docs/delicious.xml https://api.del.icio.us/v1/posts/all
machine api.del.icio.us login yourusername password yourpassword
`curl https://user:passwd@api.del.icio.us/v1/posts/recent` works just fine.
`curl https://user:passwd@api.del.icio.us/v1/posts/all` does not.
Maybe a server-side problem?
