In the case where transport_maps is used to designate the next hop destination of a message like this:
customer.domain smtp:[mail.customer.domain] ...and the customer uses round robin dns for mail.customer.domain so that it points to multiple IPs like this: mail.customer.domain. 900 IN A 111.111.111.111 mail.customer.domain. 900 IN A 222.222.222.222 mail.customer.domain. 900 IN A 333.333.333.333 ....will postfix rotate between the ips that it delivers to? Or, will it cache the first IP (111.111.111.111) and just deliver to that host until the next time postfix is reloaded or the local DNS cache for the for mail.customer.domain expires? Thanks, Curtis
