Hi Jarek, thanks for fast reply! Define secodnary MX record for the secondary MDA is one of a posiibilities :-), but i still hope there is simpler solution, something like adding another IP (the IP of secondary MDA) on each line of transport_maps :-).
Im little bit afraid of MX record solution (although it is probably the "cleanest" way), because im dont know how much i have to change my postfix configuration. Please, what do i need to change to go the MX recodrs way? There should be MX records specified inside the LAN where prim. and sec. MDA are, right? anything other need to be changed? Thank you, Jiri
