Many mail server only accept messages from machines that have a valid rDNS reccord. It looks like you are sending email from a machine with a dynamic IP, that has no rDNS, so FreeBSD mailing listr server will not accept your message. Maybe you should try to send your email through your ISP mail gateway. Best regards, Olivier
