Yes I understand. What I mean is to use example.com as an example domain, instead of mydomain.com or something. It will prevent confusion and is very helpful. For example, anyone would be able to see that you use an example and obfuscated your real domain. There is this story about how the owner of the noreply.com (or similarly named) domain received a lot of confidential email because companies incorrectly used that domain name as a noreply address. Similarly you wouldn't like spammers to harvest your supposed example email addresses such as [email protected] and abuse it. What if it is a valid address used by someone?

And if you don't you're (ab)using someone else's domains. ;-) With regards to externally reachable services an entry would look something like this: ; ; BIND data file for example.com ; $TTL 86400 @ 86400 IN SOA example.com. root.example.com. ( 20081007 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Default TTL IN NS ns1.example.com. IN MX 10 assp.example.com. example.com. IN A 333.333.333.333 assp IN A 333.333.333.333 smtp IN A 333.333.333.333 ns1 IN A 333.333.333.333 It doesn't matter much if there is a firewall in between, the server itself doesn't have to have the external IP. The firewall then has IP 333.333.333.333 and routes traffic to specific ports such 25 and 587 to the proper internal server(s). In fact that's how I have it set up at home. You would ideally want to have a reverse dns entry resolving 333.333.333.333 to smtp.example.com if smtp.example.com is the server which recipients see email coming from. Normally your ISP takes care of reverse dns, unless you have a corporate account, I would think. If so you can ask them to add the reverse dns entry.
