Author seems to report issues with the exporter and uses mtail.
mtail was developed at Google to extract from logs metrics for timeseries, and they provide an example for postfix based on the exporter rules: https://github.com/google/mtail/blob/main/examples/postfix.mtail
There is no FreeBSD port for mtail, but I can prepare one, it's straightforward enough for Go applications.
Grafana dashboard for mtail: https://gitlab.torproject.org/tpo/tpa/grafana-dashboards/-/blob/main/services/postfix-mtail.json?ref_type=heads

In any case, the exporter should run as a non-root account
