Re: [courier-users] courier not listening on port 25

tcp6 is not spurious.
If you look at the IP address columns, you'll notice that they're in 
IPv6 format - tcp6 is the same.
But the connections from the outside world, as well as from within the 
LAN, are IPv4 connections - it all just works and the netstat output is 
just a matter of default formatting within in IPv6 capable environment.
