Summary of "dnsbypass_" fields for ListManager

This table allows users to configure explicit servers to provide DNS information. This is normally used when ListManager is behind a firewall and there are mail servers also behind the firewall that should be connected to directly, without going out the firewall and coming back in. The mail server may not have a publicly known address, so this table provides a location to tell ListManager about an internal DNS server that knows about the internal-only domains.

This table also has the default root servers. If you known that your physical location is best served by a subset of these root servers the additional entries can be removed. These root servers are only used to provide a starting place if no other information is known about the domain. Removing all the root servers will cause ListManager to be unable to send mail. Providing only local DNS servers as the root server may or may not allow ListManager to function, depending on the configuration of that DNS server, but will cause it to perform more slowly. Subsequent requests for data, for example from the GTLD's, will not be asked of the local DNS server, unless these are also bypassed.
