Description

The dns_handle_mx is called when DNS query for MX record is returned. The pre_dns_handle_mx hook is called before the query result is handled. If a hook function returns 0, the remaining hook functions will be called. If all hook functions return 0, the processing of query result will continue. If 1 or 2 is returned from a hook function, the remaining hook functions and the processing of query result within dns_handle_mx will be skipped. If 2 is returned by a hook function, that hook function should free mx_routes structure. A hook function should not return any value other than 0, 1 and 2.
