Not true. (Anyway, RFC 822 defines ARPA INTERNET TEXT MESSAGES and has not anything to do with mail relaying. This is defined in RFC 821 SIMPLE MAIL TRANSFER PROTOCOL. Both 821 and 822 RFC's were updated with 2821 and 2822 respectively.) RFC 2821 Simple Mail Transfer Protocol April 2001 3.7 Relaying [..] A relay SMTP server is usually the target of a DNS MX record that designates it, rather than the final delivery system. The relay server may accept or reject the task of relaying the mail in the same way it accepts or rejects mail for a local user. If it accepts the task, it then becomes an SMTP client, establishes a transmission channel to the next SMTP server specified in the DNS (according to the rules in section 5), and sends it the mail. If it declines to relay mail to a particular address for policy reasons, a 550 response SHOULD be returned. [..] In no way it tells that you have to accept and deliver every message, i.e. to have "open email relay". Martin Ma�ok P.S. Thank you all for your vacation and out of office autoreplies. Have a good holiday! I'm very sorry I can't answer to all of you personally. _______________________________________________ Full-Disclosure - We believe in it.
