Message Text

MSExchangeTransport found invalid smart hosts string %1 on SMTP connector %2 in routing tables with timestamp %3. MSExchangeTransport is ignoring the SMTP connector.

Explanation

This Error event indicates that the Microsoft Exchange Transport service found an invalid smart hosts string on the specified Send connector in the routing tables.

When you route mail through a smart host, the smart host handles delivery to the next hop in the delivery destination. You can use an IP address or the fully qualified domain name (FQDN) of the smart host to specify the smart host identity. The smart host identity can be the FQDN of a smart host server, a mail exchange (MX) record, or an address (A) record. If you configure an FQDN as the smart host identity, the source server for the Send connector must be able to use DNS name resolution to locate the smart host server. For more information, see Understanding Send Connectors.

User Action

To resolve this warning, do one or more of the following:

  • Review the Application log and System log on your Exchange 2010 servers for related events. For example, events that occur immediately before and after this event may provide more information about the root cause of this error.

  • Resolve your issue by using self-support options, assisted support options, and other resources. You can access these resources from the Exchange Server Solutions Center. From this page, click Self-Support Options in the navigation pane to use self-help options. Self-help options include searching the Microsoft Knowledge Base, posting a question at the Exchange Server forums, and other methods. Alternatively, in the navigation pane, you can click Assisted Support Options to contact a Microsoft support professional. Because your organization may have a specific procedure for directly contacting Microsoft Product Support Services, be sure to review your organization's guidelines first.
