I guess there is no real chance without conntrack ... I'll try to use something like LVS+mysql conntrack (no idea if this even exists ...) ....

Subject: Anycast provider for SMTP?
I have a mail system where there are two MX hosts, one in the US and one in
Europe. Both have a DNS MX record metric of 10 so a bastardized
round-robin takes place. This does not work so well when one site goes
down. My solution will be to place a load balancer in a hosting site
(virtual, of course) and have it provide HA. But what about HA for the
LB? At first glance anycasting would seem to be a great idea but there is
a problem of broken sessions when routes change.
Have any of you seen something like this work in the wild?
