smtpd.conf on OpenBSD: how to say "internal network"?

[Harald Dunkel]

Hi folks,

hardwired constants in my smtpd.conf are causing problems with IPv6
prefix delegation, so I wonder if there is some abbr. for "internal
network"? Something like

        # table localnet { 10.10.10.0/24 10.10.11.0/24 2001:db8:abcd:0012::/64 }
        :
        listen on intern tls pki $xname
        listen on extern tls pki $xname
        :
        action "relay" relay
        # match from src <localnet> for any action "relay"
        match from src (intern:network) for any action "relay"
        :

(similar to pf.conf on OpenBSD)? "intern" would be the interface group
configured for all internal network interfaces.

I tried

        # table localnet { 10.10.10.0/24 10.10.11.0/24 2001:db8:abcd:0012::/64 }
        :
        listen on intern tls pki $xname tag INTERN
        listen on extern tls pki $xname tag EXTERN
        :
        action "relay" relay
        # match from src <localnet> for any action "relay"
        match tag INTERN for any action "relay"
        :

Doesn't work :-(. If I enable the old "localnet" lines, then it does.

Hopefully I am not too blind to see, but I haven't found this in
smtpd.conf(5). Every helpful comment is highly appreciated.
