It certainly deserves to be accessible; if Adam agrees? Blush, sure I have no problem with that at all. I have since thought of one or 2 additions I should have made though. 1) If your ISP allows and many don't, you should set up a reverse DNS record (you need to do this with your ISP, not ZoneEdit or whomever you did your other DNS stuff with, since they own the IP address and therefore answer the DNS lookups on it. Reverse DNS records are called PTR records and map your IP address back to a hostname rather than the other way round which you have (theoretically) already set up. You need to do this if you plan to host mail since some mail servers check your forward (hostname to IP address) and reverse DNS records (IP address to hostname) and reject your mail if they don't match. So, set up a PTR record with your ISP that matches the A record you provided for the server named in your MX record, aka mail.silverrook.co.uk. 2) If you to run your server on a DMZ instead of your main LAN, Windows style Samba file sharing won't work as it relies upon a lot chattery communication between the hosts and being on a DMZ doesn't allow your server to initiate communication with the main LAN.
