By parsing Received header fields. Even if last mail hops were over IPv4, a mail message may still have traveled through, or be submitted from an IPv6 address. Besides in a mail header section, IPv6 addresses may be present in URLs found in a mail body, or be fetched indirectly through DNS lookups. One can no longer live in a padding of an IPv4-only installation, thinking that IPv6 won't be affecting him. Mark
