The mail server that serves the list does not allow posting from IP addresses that do not generate a hostname. Unfortunately there is not much you can do... it is your provider that does the reverse for it. If they listen... you can try and ask them. -- Matt Gostick http://www.crazylogic.net/~matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
