The POSIX.1g draft networking API and associated IPv6 work have
cleaned up the API around finding names and addresses. You get
getaddrinfo() and getnameinfo() which give you nice generic
structures that cope with all sorts of name and address types.
Since it looks as though exim has some IPv6 support in it (though
I haven't looked closely) it might be worth thinking about the new
get{addr,name}info() API.
