dsync doesn't need existing indexes, it wants to create indexes. If it
can't because of e.g. permission issues, you should be able to work
around it with:

dsync mirror mbox:~/mail:INDEX=/tmp/indexes

I might change dsync at some point to work even without permanent
mailbox GUIDs, but there are many other more important things to do.
