Because (for tcp at least) there are packets going both ways. How can a
packet for a ip that your host doesn't announce find it's way to your box?
The switch infront of your host 'knows' only of one of your machines owning
that CARP ip.

- CARP is not intended for this.
- Please tell us what the real problem is that you want to solve
- Why can those two host not use their host address for outgoing mail?
- Take a look at hoststated(8)
