Description

The dns_handle_a is called when DNS query for A record is returned. The post_dns_handle_a hook is called after the query result is handled or the processing logic in dns_handle_a is short circuit when a pre_dns_handle_a hook function returns 1 or 2. The hook function must check if mxinfo is NULL or not before using it.
