Mailbox name should probably not start with a '.'.  I'm assuming it is a 
maildir storage. The physical mailbox directories in that maildir have a 
'.' prefix, but the actual mailbox name does not: it should be 'INBOX.iop'.

Something like this:

require ["fileinto", "variables", "mailbox"];

if address :matches "delivered-to" "*" { set "delivto" "${1}"; }
if address :matches "to" "*" { set "to" "${1}"; }

if not string "${delivto}" "${to}"  {
     fileinto :create "INBOX.iop";
     stop;
}

For reference you can read RFC5229 (http://tools.ietf.org/html/rfc5229).
