No, I mean what will you do when people respond to your synthesized
names?  At some point you'll get mail at the server for mydomain.com
for yahoousername-AT-yahoo.com at mydomain.com.  What will you do with it?

One of the reasons I did the .invalid hack (which you can do with
essentially the same code you're using) is that it's clear that the
address isn't deliverable so there's no question of what happens to it.
