Local Internet Domain Smarthost and DNS Problems

We have configured a Local Internet Domain Smarthost in our Configuration document under Router/SMTP->Basics to point to an external SMTP mail server.According to the documentation, any mail sent to a user in our local domain that cannot be found in the Notes directory, should be forwarded to the Smart Host.

I send an email to a nonexistent user nobody@domain.com, and this is what I get on the Notes console:

16/05/2005 14:07:49 Recipient in local Internet Domain not found, forwarding to Smart Host

16/05/2005 14:07:49 DNS is unavailable, message will be requeued.

The message then sits in the mail.box and never gets delivered.

I cannot figure out what it is looking for in DNS. nslookup from the server works. I added MX records for the domain.

I did a trace on the DNS server, but I don’t see any request from the Notes.

I added the DNS host under HKLM\System\CurrentControlSet\Services\Tcpip\Parameters\NameServer like I saw in some help articles.

Is this a bug, or am I missing something?

Thanks,

Moshe

Subject: Local Internet Domain Smarthost and DNS Problems - Resolved!

I collected all the previously published advice, and tried again. Here’s what seems to have done it:

  1. Add DNS address under HKLM\System\CurrentControlSet\Services\Tcpip\Parameters\NameServer

  2. Delete all extra adapter and interface entries under HKLM\System\CurrentControlSet\Services\Tcpip\Parameters

  3. Disable unused adapters under Network Connections

  4. Reboot server

I see that after reboot the interface entries return, but the adapter entries do not. I also tried lowering MTU, but then restored it to default and it still works, so that was not it.

Anyway, hoped this helps someone.
