And Ident - port 113

[Robert Moskowitz]

I also have ident - port 113 open on the firewall.  But not only is it 
not open on the server's firewall, I don't see a listen for it with 
'netstat -na|grep113'

I do recall that ident was one thing some MTAs wanted.  Is that still 
so?  And if so, should I see a listen on it?
