Ok, thanks for the explanation i undersnand it more know.
The A queries comes from postfix because this:

reject_unknown_recipient_domain
    Reject the request when the recipient mail address has no DNS A or
MX record. The unknown_address_reject_code parameter specifies the
response code for rejected requests (default: 450). The response is
always 450 in case of a temporary DNS error.

But i'm wondering why postfix is rejecting a domain with a valid MX?
Well as a workround i'll quit the restrictions.

Thx
