Name lookup failure handling(dnsforcetemporary, nodnsforcetemporary)

When attempting to make an outgoing connection, name lookups that return a "host not found" or "no addresses" sorts of errors are normally treated as permanent failures. The dnsforcetemporary channel option, which places on the dequeuing channel, alters this behavior and causes this errors to be treated as temporary. nodnsforcetemporary is the default.

Important note: This restricted option is only intended for use in special situations where the list of possible remote hosts is tightly controlled. Use in other situatiions, especially ones where users are able to specify the remote host, will lead to delays in reporting failures conditions.
