Just out of curiosity, why are you load balancing SMTP at all? In my
experience, the number of circumstances that absolutely require SMTP
load balancing/clustering are very rare, given that the protocol has
fault tolerance and failover built into it. In fact, load-balancing
SMTP hosts can actually cause slower deliveries and unpredictable
behaviour, because it can conflict with the protocol's own resilience
features.
Even where it is needed, I'd prefer smtp proxies over LVS.

A problem shared brings the consolation that someone else is now
feeling as miserable as you.
