Hi Ralf, Thanks - I now have... --- /etc/postfix/main.cf: # transport_maps = hash:/etc/postfix/transport relayhost = [our_isp_mailrelay]
/etc/postfix/transport: #<our_own_domain.com> smtp:<our_external_hosted_mailserver> #<servicepartner1> relay:<our_isp_mailrelay> #<servicepartner2> relay:<our_isp_mailrelay> #<servicepartner3> relay:<our_isp_mailrelay> #<servicepartner4> relay:<our_isp_mailrelay> #<servicepartner5> relay:<our_isp_mailrelay> --- When i put this to production, my config should be like this, right: --- main.cf transport_maps = hash:/etc/postfix/transport #relayhost = [our_isp_mailrelay] /etc/postfix/transport: <our_own_domain.com> smtp:<our_external_hosted_mailserver> <servicepartner1> relay:<our_isp_mailrelay> <servicepartner2> relay:<our_isp_mailrelay> <servicepartner3> relay:<our_isp_mailrelay> <servicepartner4> relay:<our_isp_mailrelay> <servicepartner5> relay:<our_isp_mailrelay> --- All our mail are going through to our_isp_mailrelay today, so I no longer need the "relayhost = [our_isp_mailrelay]" in main.cf when I have configured transport_maps - or how does this work ?
