I am no mail expert, but I reasoned that the target mail host is doing a reverse name lookup to verify the sender, and when this check fails the mail is bounced. With the mail relaying through my ISP mail host, the remote sendmail is happy. BTW, I have never had mail bounce from the mail host(s) at freebsd.org due to this. However, nearly everything sent elsewhere bounces when not relayed through my ISP mail host. Is freebsd.org's leniency due to the number of messages sent from hosts like root@myname.my.domain that would bounce otherwise? -- Allen Campbell allenc@verinet.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
