"universal" DNS server
Hello,
I am using Infradig Mail as the local mailserver on my machine. If I do not enter a DNS server, mail is not sent - however if I enter the DNS (and alt. DNS) of my ISP, it works. However, I primarily installed the mailserver in order to be able to send mail independent from the ISP I log in with.
a) is there a DNS server that works with each ISP?
b) any alternatives are greatly appreciated, as well!
b) any alternatives?

almiller, thanks for your comment!
I just tried to log in via a local ISP and entered CompuServe's DNS servers in the ini filed for Infradig. Sending mail failed, the logs showed "no DNS entry". If I insert the DNS of the local ISP, it seems to work - but only if I connect via this ISP. Maybe these DNS are only available when connected via the appropriate ISP?! Any ideas?

It is possible if they provide some sort of local IP address. What is the IP address of the DNS?
I'm not familiar with the programs you are using, maybe they have different needs.
My comment was accurate on situations when you have complete and full access to the Internet. In that case you should even be able to use my DNS on my LAN since we are not behind a firwall or anything else.
Once connected to the Internet, can you ping 192.116.192.8 or 192.116.192.9 or 192.116.231.45?
Try running nslookup and when you are at the > prompt try switching server by typing:
server 192.116.192.8
and see if you can lookup domains

I am not familiar with Compuserve architecture and policy, but unless they are creating a completly new DN, it should matter if you are using thier DNS or someone else'.
According to jhance they simly block you from accessing it outside, but you shouldn't be prevented from using another, non-Compuserve DNS. It wouldn't make much sense because of latency, but it shouldn't be imposible.

I for example, have installed a DNS on my local network to shorten access time to my DNS. This is a dramatic improvment for DNS lookup for all clients on the local network (ping time to the ISP's DNS is around 50ms).
To answer your question, you can use any DNS when connected to any ISP, but for good performance you should find out which is the closest to you, and that (usually) is the ISP's.
There are, of course the root NS (a.root-servers.net, b, etc), but they mustn't be used as regular DNS, but more for tld queries.
