tcpserver and ip binding

[Messiah]

Hello all,

I want to run 2 instances of qmail-smtpd thru tcpserver. One instance should bind to a specific ip, the other instance should bind to all other ip's. Is this possible? If yes, how?

I mean, I know how to bind to a specific ip, that would be like this:
tcpserver $options $interface $service $command
and interface would be:
0: any interface
IP address: bind to this IP only

But this does not work for me, this means that I have to run a lot of instances and bind to all ip's one instance, and I don't want that.
