Your fix for this differs from mine. It accepts IPv6 literals even when
IPv6 isn't configured in -- which is OK, I suppose -- but it also
accepts IPv4 addresses with of the form [IPv4:xx.xx.xx.xx], and IPv6
addresses _without_ the 'IPv6:' prefix; neither of which I see
documented in RFC2821. Is this intentional permissiveness?
