move faster? ;]

if you move it to another IP space then lower TTL for that machine record in your
DNS zone 

if you have:

		IN 	MX	10	mail
mail		IN	A	192.168.1.1

change it to to

		IN	MX	10	mail
mail	15M	IN	A	192.168.1.1

so if you change IP for mail to another IP that change will be seen in
15 minutes! And DO NOT forget to change the serial in SOA record!
