Well, we get email probs if the recipient domain is on the opendns list of things to block. Its blocks at the DNS level so will happily block MX as well as A records. Updates have never taken more than about 1 hour for us though.
From: James Rankin [mailto:[EMAIL PROTECTED] Sent: 13 August 2008 13:47 To: NT System Admin Issues Subject: OpenDNS Does anyone on the list have any issues with OpenDNS? I recommended this to a friend of mine, and it appears to be behaving rather strangely. When it is enabled in their DNS forwarders, it appears to block email as well as web traffic to domains such as hotmail.com and btinternet.com - as soon as the DNS settings are removed, the Exchange queues clear. Also he made some changes to allow webmail in his OpenDNS settings, and six hours later, they are still getting blocked when browsing to hotmail.com or Yahoo mail. I have sent a few requests to their support teams, but haven't even received as much as an auto-response yet.
