I can say this right off:  Encoding the timestamp as an integer with an anchor year is going to be a problem (e.g in 2038 or 2106) requiring a future version upgrade.  Consider a split timestamp:  One value in seconds since the beginning of the current year (25 bits required), and another for the cardinal number of the year itself.  A 32-bit year as a separate value should last about as long as the Earth itself is expected to.

For the extra 7 bits in the seconds value (as a 32 bit value total), one could encode 3 of them for the day of the week as a "verifier" value.

Maybe you don't care about the 27-year timebomb you're giving yourself.

IP-address-types:  Consider adding as a separate value "spamtrap" that occurs as a result of delivery to a spamtrap address.  Such may be classified without passing through a filtering system.  It is a case that should be distinguished from #3 (filtered auto-spam) or #7/#8 ([in-]valid recipient).

Section 8 - Example Report:  Should use an IPv6 address from the documentation prefix (2001:DB8::/32) instead of a live address.

Those were the only three things I saw worth commenting about.
