We're running PGP WDE with a Universal Server. The server is not open to the outside world. Typically, this is not a problem, and laptops that leave the office don't complain. However, I have two people staying at a hotel this week that apparently uses OpenDNS. They're getting the following certificate error: "Server pgp-svr.company.com presented a TLS certificate for a domain name which does not match (*.opendns.com)." It then wants an Allow or Deny. Denying only delays the next error; they're getting them a few times an hour.
I have seen that OpenDNS can do that, at least for HTTPS that it can't resolve. Since I obviously don't control their OpenDNS settings, that doesn't matter much.
Apart from not staying at that hotel, is there a way to prevent this?
