Because the compressed form is what Postfix logs, therefore the compressed form is what Postfix uses for access map lookups. If Postfix were to use form X for logging and some unspecified different form Y for access map lookups, then that would be a real WTF. Instead, Postfix documents how it derives lookups from the from X. Again, I recmmend using cidr if you need control over the matching process. Wietse
