I don't think the mbox file should be modified if it's not locked. I
suppose it's not very ideal either if user can't delete mails then, but
at least the mailbox doesn't get corrupted.

Anyway, you most likely don't really need to use dotlocks at all. Just
make sure that your MDA uses fcntl locks and set mbox_write_locks=fcntl.

Also I think Dovecot v1.1 should be able to open the mailbox read-only
even if it can't create the dotlock? Are you using v1.0?
