To recognize an email address, Postfix compares the content of two character strings stored as a sequence of octets. One character string contains "double-bounce" and the other contains informatiom from an email address that resolves to the local domain (matches mydestination or inet_interfaces). "to discard" means "to throw away". Wietse
