In the SMTP daemon, "unknown" means that the reverse/forward match
failed. This can happen for three reasons: reverse lookup failed,
forward lookup failed, or the match failed. Additionally, the SMTP
daemon distinguishes between temp-failed and hard-failed lookups.
Are you asking for six different "unknown" variants? Why is that
an improvement?
It's another reason to make logging configurable.
