Hello I have such a solution: 1)One serwer to incomming 2)One server to outgoing
All Customers in their mail clients (outgoing) use adress: smtp.foobar.org In main.cf I use smtp_bind_address - for default IP send and sender_dependent_default_transport_maps (for indiwydual IP) works fine. Is any change to "auto changing" IP in smtp_bind_address ? I know this is a stupid question but I have some problem with throttling with send e-mail to *.protection.outlook.com if I change IP in smtp_bind_address (RBL, for example) I think about sharing users and group addresses for sending mail - but maybe is simpler solution ? --
