`NoReverseMatch`: `django_mailbox` uploads are incompatible with `downloadview`
Previously email attachments were automatically the django_mailbox
module.
These files were stored somewhere below mailbox_attachments/
in the media directory.
Such file names cause a NoReverseMatch
.
One of the following approaches should be suitable for fixing this issue:
- A) use a URL specification, which allows multi-level filenames (currently only flat filenames are allowed)
- B) migrate all old files to the new filename schema
