Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG My sendmail is rejecting email for some strange reason. I am not sure exactly why it is refusing this particular email. The host that it is coming from is "131.137.96.18" which resolves into "mail.dnd.ca". The only thing that I can see is that dnd.ca is different than the originating host. But at the same time there is a MX record for dnd.ca as follows: Non-authoritative answer: dnd.ca preference = 10, mail exchanger = mail.dnd.ca Authoritative answers can be found from: dnd.ca nameserver = ns.dnd.ca dnd.ca nameserver = ns1.drenet.dnd.ca dnd.ca nameserver = gps1.ndhq.dnd.ca mail.dnd.ca internet address = 131.137.96.18 ns.dnd.ca internet address = 131.137.255.2 ns1.drenet.dnd.ca internet address = 131.136.242.3 gps1.ndhq.dnd.ca internet address = 131.137.96.3 Here is a copy of the maillog.
