Yes. You can also give -o mdbox_rotate_size=X parameter to dsync to override the config. The mdbox_rotate_size is started to be used immediately, so if you increase it Dovecot may start appending new mails to old files. The existing files aren't immediately shrunk, but during purge when writing new files the files can become smaller.
