* Attachments that come in with a file:// URI do not support the complete
set of OpenableColumns columns. To handle this better:
1. Obtain the openable values in two separate queries, in case one or
the other is supported (but not both).
2. If the size is not reported but it is a file:// URI, attempt to
measure it directly.
3. If the size cannot be obtained, do not upload the attachment
