Re: E-mail example a bunch of crap said by bn1221:Real email hosts should use their own caching DNS or use business grade DNS that doesn't do a redirect. I use OpenDNS redirects but my email system hits ATT DNS directly. Bounced emails take less than 30 seconds. In my experience, any sizable sending or receiving domain should typically have DNS servers that are dedicated to their mail application. In no small part this is to ensure that enough DNS query capacity is available exclusively to support the mail flow. You wouldn't want DNS queries for web surfing traffic (or whatever) to cause DNS queries from the mail servers to take too long or to time out and fail. Smaller domains should use non-redirecting DNS IPs, as another poster pointed out above.
