I thought check-state was fairly optional; ref:
These dynamic rules, which have a limited lifetime, are checked at the
first occurrence of a check-state, keep-state or limit rule, and are typ-
ically used to open the firewall on-demand to legitimate traffic only.
See the STATEFUL FIREWALL and EXAMPLES Sections below for more informa-
tion on the stateful behaviour of ipfw.
(from "man ipfw" on a 4.11 system).
Peace,

Mail filters, like sewers, need to be most restrictive at the point of entry.
