Problems with Postfix / Round-Robin

Hi all!, I am new in the forum. Please excuse me for my bad English.

What I want to do is to set up a round-robin from the Postfix to various exchange servers

| EXCH 1 (10.0.0.207)
Inet => Postfix |
| EXCH 2 (10.0.0.208)

I define the round-robin in the local Bind, and when I ping to the MX name I do get a response from each server.
The problem is that when I send mails to the postfix, for example 1000 mails, It routes 990 to one of the exchange (10.0.0.208) and 10 to the other one (10.0.0.207).
I alter the order of the A records to see if it changes, but did not.

In the maillog the only difference I see is that the "delay=x" value in the 10.0.0.207 server is a very high number (40) and for the 10.0.0.208 server is 0.18 aprox.

Does anyone know whats going on with it?

Regards,

Pablo.-
