My point being that I totally fail to understand why having this hostname resolve to a private IP will allow mail to be delivered, and having it not resolve within the public DNS should cause mail delivery to fail. From the perspective of hub.freebsd.org both situations have the same result. > In such a case, your organisation will provide a mail gateway for > your domain and internally sourced mail should rewrite addresses as > if they originated from this machine. Point me at a reference that says so. There is no such requirement as far as I am aware. Also, the hostname of this box does not appear in the addresses - they are rewritten so as to be deliverable, thank you. The only time the hostname of this machine ever crops up in the SMTP dialogue is in the EHLO line. Are you still telling me that mail is not being rejected on this basis ? > You should also arrange for these internal hosts to collect their > mail from the mail gateway and not expect it to be routed. I route the incoming mail to this box just fine thank you, ``collection'' per se is not necessary. > The action of hub.freebsd.org is normal in attempting to check that > the supplied IP address matches that of a host lookup - for a system > that employs relaying controls. Perhaps. But it _is_ in direct violation of RFC1123 and I do wish you would stop trying to tell me that it isn't. Ceri -- I probably wouldn't like you. Really. I really probably wouldn't like you.
