Hi, Thanks a lot to all of you (Ralf, Stefano and Appliantologist) for your great support !!!
I think I'll use the Ralf solution as I don't have to maintain any additional list , by just putting: luser_relay = $u...@[ip_address_of_old_server] local_recipient_maps = All the mailbox not yet localy created on the new server will be forwarded to the old. Thanks Again to all, you saved my new weeks !
