Not. Really it is working since yesterday, so haven't still background 
enough, but the default politic in load balancer is to share the load 
between both servers, so around 50% of message goes to each servers, but 
is not perfect; and cannot be guaranteed for an individual user 
messages.

Ratelimit is implemented in our outgoing mail servers (for incoming 
mail we are using milter-greylist for some years with great results in 
another servers), so I'd like to say our users *exactly* how many 
recipients they can send messages each day.

Let's suppose a limit of 1000 is specified and publised in internal 
mail "Terms of use". In normal work, I can specify a ratelimit of 500 in 
each server and the global limit will be more or less accomplished (not 
perfectly, as the load balance is not). But if a server crashes or is 
put offline for update/upgrade, the limit will be 500, too far of the 
specified limit.

Hope I have explained well enough (not English native speaker; 
greatings from Spain)
