Error Sending Emailonline Mail For Some Remote Domains

This issue can occur if the remote DNS servers ignore the AAAA request or return an unexpected response.

To work around this issue, create assigned remote domains for the ribbon. (Create a connector redirector for each domain). Then, no doubt, configure Send connectors to use the remote domain’s email web host as an efficient host. To do this, follow these steps:

1. Check the IP address of the MX movie (mail server) for the affected remote zone. Use or nslookup Look up MX records .
2. Create a new connector for this domain. Make sure to configure the settings:
3. In the Address Store section, add the affected remote domain, such as contoso.com.

2. In the network settings, select the smart mail routing option using the following types. Usually add the IP address of the MX record that you verified in your personal step.

You can use the default for other settings. AdditionalFor details, see Configuring a Dedicated Send Connector for a Specific Domain .

As you can see, when Exchange Server sends email to this type of remote domain, it bypasses the request DN and directly connects to the remote domain’s web email server using the IP address.

When You Email Me On All Remote Problem Domains, An Error Occurs

This can happen because the DNS server used by Microsoft Exchange Server is down. By default, Exchange uses the DNS settings on the server’s network adapter to route outgoing remote e-mail.

To resolve this issue, troubleshoot a new local DNS server or configure an external DNS server to route mail remotely. Follow these steps to configure an external DNS server to remotely manage mail routing:

1. Open the Properties page of the Exchange server that owns the Send connector, then add most of the DNS IP address for public. servers < / a> addparameter for external DNS lookup.

2. Select the option “Use exact lookups for external DNS settings on servers, and the option for transport role in the connector that is responsible for the most important remote routing.”

• Question

• I have a problem sending emails to a specific trusted domain.

  Let’s call it the problem domain for discussion.

  I can only give and receive names from others.

  I am using SBS 2008 with Exchange 2007

  I am using DNS to getAnd I also checked the box on the Network tab of the Send Detector Network tab to use the external transport DNS lookup settings for the DNS server that is on the DNS server of my ISP board.

  When I open nslookup from this command line, I get

  C: Windows system32> nslookup
  standard server: unknown address
  : fe80 :: 1d11: 6c69: c59: 9c72

  so I say use it for IP

  > Server 10.202.2.220
  Standard Server: [10.202.2.220]
  Address: 10.202.2.220

  > eauctions.ie
  Server: [ 10.202 2.220]
  Address: 10.202.2.220

  

  Answer:
  unauthorized name: problem domain.ie
  Address: XX.XXX.XXX.XX <- the correct It-IP

  and dissolves well.

  When I check the connection log, I see the following image

  CC9CC817F1FDB6, SMTP, problemdomain.ie, +, 97d0d5db-0bc1-426d-b9e4-347c59db8bbe

  Then I see that his Sen SMTP connector is using the external server’s DNS, no cannot connect to the server.

  If I then put this particular server in nslookup to manage the insert, I get the following

  

  C: Windows system32> nslookup
  Standard Server: Unknown
  Address: fe80 :: 1d11: 6c69: c59: 9c72

  > Server 85.91.1.129

  > collection q = mx
  > problemdomain.ie
  server: [85.91.1.129]
  Address: 85.91.1.129

  Unauthorized response:
