Postmaster@localhost.localdomain rejected for policy reasons

I am seeing some weird behavior with our domino server.

I have to remove the mail.box file and restart domino at least once a day.

Email seems to be working just fine on the server once I restart domino.

I am seeing a lot of errors that look like:

postmaster@localhost.localdomain rejected for policy reasons. Relays to recipient’s domain denied in your configuration.

Maybe this is the root of our problems. We have about 10 users on the server.

etc/hosts file looks like this:

127.0.0.1 host localhost.localdomain localhost

Here are some console entries that look strange.

Thanks for the help.

It looks like someone or something is trying to connect to Notes and route mail to postmaster@localhost.localdomain and/or notes@localhost.localdomain …

Check to see if there is any antivirus or something like that running on the box that might be trying to do that. You should look to see what IP that connection is coming from and try to determine what it is.

Is the mail.box full before you restart the server? After? Have you tried just restarting the router? What error message/symptoms are leading you to restart the server?

The system is acting as if your loosing your MX record configuration or atleast your PTR record. Many firewalls are setup to deny traffic that does not list a corresponding PTR (reverse arpa record)for the mail server.

In essence either your server is refusing to tell the recipient that the mail originated from your server so it looks like probable spam. This is very common with Cisco PIX and a minor problem with a couple of other brands but it depends on how the DNS, MX and Firewall is setup. Any of those three could be at fault. Though I understand that the MX record is in the local DNS its also zoned at the ISP level as well.

Check your system out at www.DNSstuff.com and check that MX record, first.
