Explanation

This Error event indicates that the Microsoft Exchange Transport service SMTP Receive component can't process an SMTP message submission from a particular user.

The Microsoft Exchange Transport service controls the sending and receiving of messages in Microsoft Exchange Server 2010. The Exchange 2010 transport pipeline uses the SMTP Receive component to validate the message content before the message can be submitted to the Submission queue. The SMTP Receive component applies a series of receive events and, if configured, antivirus and anti-spam events to validate the message. Additionally, the SMTP Receive component contacts the Active Directory directory service to validate users who submit messages for delivery. This includes connections to route internal users' messages among servers.

This event represents an authentication error for a user who tries to submit an SMTP message. This event could be logged in one of the following scenarios:

• The user does not have sufficient rights to send as a particular user.
• The Default connector does not have the Accept any Sender permission set for Authenticated users.
• The network settings on the Default receive connector do not include the IP address range of an IMAP4 or POP3 client that tries to submit messages.

User Action

To troubleshoot this issue, do one or more of the following:

• Überprüfen Sie das Anwendungsprotokoll und das Systemprotokoll auf den Exchange 2010-Servern auf verwandte Ereignisse. Ereignisse, die unmittelbar vor oder nach diesem Ereignis auftreten, können z. B. weitere Informationen zur eigentlichen Ursache dieses Fehlers zur Verfügung stellen.
• Review the Operations Console in Operations Manager for detailed information about the cause of this problem. For more information, see the "Introduction" section in this article.
• Enable diagnostics logging on the affected receive connector. To do this, follow these steps:
  1. Run the following commands from the Exchange Management shell:
     Set-ReceiveConnector "name of connector" -ProtocolLoggingLevel Verbose
     Set-TransportServer Exchange01 -ConnectivityLogEnabled $true
     Set-TransportServer "Exchange01" -IntraOrgProtocolLoggingLevel Verbose
  2. After Event ID 1026 is logged, examine the SmtpReceive log file. By default, this file is located in the following directory:
     %ProgramFiles%\Microsoft\Exchange Server\V14\TransportRoles\Logs\ProtocolLog\SmtpReceive
• Examine the authentication settings on the receive connector. To do this, run the following commands from the Exchange Management Shell:
  Get-ReceiveConnector "Exchange01\default Exchange01" | fl *
  Get-ReceiveConnector "Exchange01\client Exchange01" | fl *
• Assign the user Send As permissions to the mailbox. To do this, follow these steps:
  1. Start the Exchange Management Console.
  2. Expand Recipient Configuration, and then click Mailbox.
  3. Click the affected mailbox, and then click Manage Send As Permission in the Actions pane.
  4. Click Add, and then add the user to the mailbox.
     You can also run the following command from the Exchange Management Shell to assign the user Send As permissions to the mailbox. To do this, run the following command:
     Add-ADPermission -Identity 'CN=User1,CN=Users,DC=tailspintoys,DC=com' -User 'TAILSPINTOYS\User2' -ExtendedRights 'Send-As'
     In this command, User1 represents the name of the affected mailbox and User2 represents the name of the user who should have Send-As permissions to the affected mailbox.
     For more information, see Verwalten der Berechtigung "Senden als" für ein Postfach.

  • CN=Microsoft Exchange
  • CN=<Organization>
  • CN=Administrative Groups
  • CN=Exchange Administrative Group
  • CN=Servers
  • CN=<ServerName>
  • CN=Protocols
  • CN=SMTP Receive Connectors
  1. In the details pane, right-click the appropriate connector (for example, CN=Default <ServerName>), and then click Properties.
  2. Click the Security tab, click Authenticated Users, and then click to select the Accept any Sender and Accept Authoritative Domain Send check boxes in the Allow column.
• Use the Exchange Management Console to verify the network settings on the Default receive connector. To do this, follow these steps:
  1. Start the Exchange Management Console.
  2. Expand Server Configuration, click Hub Transport, and then click Receive Connectors.
  3. Right-click the Default <ServerName> connector, and then click Properties.
