Does it just issue the command via IMAP?  No direct filesystem

Yeah, that was mostly me being lazy in my wanting to deal with escaping,
so I just ignored them.

In what I originally wrote, I think it just won't touch them.

Or is the issue that the find command might remove them and then the
indexes don't get fixed up?  I suppose I could just make sure that the
find ignores those dirs, but I thought (from other maillist reading)
that the next time their client SELECTs the folder it'll fix it up

I suppose another spin on this would be for me to script the preauth
imap client to figure out which mailboxes have messages marked for
deletion of such and such an age and then try to use EXPUNGE to wipe
just them out.  I'm not sure off hand if that's possible.

I suppose that's what doveadm already does.
