This will call inet_connect() (in util/inet_connect.c). This calls
the getaddrinfo() system library function to look up the IP address
for the name (which typically involves nsswitch), and then tries
each IP address until a TCP connection can be established.
Once a TCP connection exists, it WILL NOT try another IP address
for example when the Milter is responding incorrectly.
