The tests that can get thrown at your system is to see whether your MTA accepts or rejects the mail. If it rejects it then it gets no further. If it is accepted then it means that persons MTA will relay it, in the case of the test messages, they will receive a message back instead of the reject code(s). So what is it you are trying to prove ? That they send a reject message, but secretly accept the message and relay it ? Please explain, because I cannot make any sense of what you are asking. -- Regards Cliff To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
