This may be to do with my server config at siteground (which I don't have much access to) but after two evenings of attempting to solve the problem I'm still getting the same error messages when trying to harvest from email, place in a directory and attach to a CCK field.
I've tried changing permissions and different directories.
The selected file /tmp/fileTym9vL could not be uploaded, because the destination is not properly configured.
