Hi all! We're using Postifx as described in the configuration examples [1] for an email firewall/gateway delivering the emails to an internal non-Postfix smarthost.
Now we're updating our internal core infrastructure by installing two new smarthosts for failover and load balancing, but as far as I understand it's not possible to configure transport_maps with more than one gateway for the same destination. As I understand the options we have here are: (1) switch from transport_maps to relay_domains which introduces the problem that it'll also accept mail for 'anything.example.com' (as described in the documentation) or (2) install bind in the Postifx relay server as described here http://marc.info/?l=postfix-users&m=118254039015052&w=2 due that we don't have a name server in our dmz. Do we have any other option ? I'd like to keep our current configuration without installing bind for just this purpose. Thanks in advance for any advice. JC. PS: any chance of adding support in transport_maps for multiple smarthosts with same destination ? [1] http://www.postfix.org/STANDARD_CONFIGURATION_README.html#firewall
