Assuming that people will extensively use the domain system to publish current routing information for mailboxes and dealing with cacheing and all the other problems is expecting too much. The idea is a nice one alas a very flawed one (from too much data). The trick at this pont is to just get a reasonable mail relaying mechansim up and to get rid of the host table. The MX records solve in a not so great way the problem of mail relaying for hosts not on the connected network alas a better algorithm has not been thought up that did not get shot down (heck, we can not even get packet routing right...how do you expect to get mail routing right?) Also many places are still using the host table mechanism and are starting to suffer because of the size problems....alas they have received temporary relief in the form of a 10% smaller NIC table. Let us keep an eye toward the future but make that first couple of steps instead of just dreaming about the future.... -Rudy
