Worth reading: http://www.hardwarefreak.com/postfix-adsl-relay-config.txt That covers the Postfix outbound setup so your mail isn't blocked by everyone due to dynamic IP status. This relays mail through your ISP, just as you would with Thunderbird, Outlook, etc. The inbound setup simply requires something like TZO dynamic DNS service, which I used for many years and it worked flawlessly. Any dyndns service that allows using a real domain.tld will work. Make sure your consumer router is doing dynamic IP updates to the dyndns provider. Create an MX record with the FQDN of your mail host. Since dyndns services provide wildard resolution, you do not create an A record for the MX host, just the MX record. Make sure your router is port forwarding TCP 25 from the WAN interface to the RFC1918 address of your Postfix server, and that's about it. -- Stan
