What I feel from reading documentation [1][2] is that they could be dropped in the backups, to be recreated on the fly if needed. If you are using maildir, then yes, that's my understanding too, those files don't contain data that doesn't exist anywhere else. But beware

<sigh>
Both of the responses to your question apparently missed that you are using mdbox.
Obviously you can NOT ignore/delete the index files for dbox storage formats, but I'm not sure about the cache files.
I *think* you can ignore them, but I'd have to defer to someone else for a definitive answer, and I'm definitely interested in the answer to this too since I'm considering migrating to mdbox myself.
