none of this will block spam. spammers do not follow RFC 974 today (since i see a lot of them come to my A RR rather than an MX RR, or in the wrong order). any well known pattern that says "don't try to deliver e-mail here" will only be honoured by friend people who don't want us to get e-mail we don't want to get. -- Paul Vixie KI6YSY
