I'm wondering if there should be "all-ipv4" and "all-ipv6" values to
complement the "all" value and allow independent configuration of IPv4
and IPv6 without having to specify literal IP addresses. This would make
"all" equivalent to "all-ipv4, all-ipv6". Just a thought bubble...

By supplying an IP4 address and not an IPv6 address, you are
effectively leaving the IPv6 setting blank. What happens with a blank
field needs to be specified.
how is "inet_interfaces = all" different to "inet_interfaces = 0.0.0.0
::"
The docs mention setting smtp_bind_address to 0.0.0.0 but don't say
what will happen if inet_interfaces is set to 0.0.0.0 [::].
by having the "all" option, it seems to imply that receiving mail can
be disabled on either stack by not supplying an address. Is that what
will actually happen, or will Pf default to something?
