You receive an NDR #5.4.0 when you send an e-mail message by using the SMTP connector in Exchange Server 2003



SYMPTOMS
When you try to send an e-mail message by using the Simple Mail Transfer Protocol (SMTP) connector, you may receive a non-delivery report (NDR) that is similar to the following:
The destination server for this recipient could not be found in Domain Name Service (DNS). Please verify the email address and retry. If that fails, contact your administrator. < HostName.DomainName.tld #5.4.0>
Note tld is the top-level domain name.
CAUSE
This issue may occur when the following conditions are true:
  • The SMTP connector is configured to forward e-mail messages to a smart host, and the SMTP connector has the Queue mail for remote triggered delivery option turned on.

    Note The Queue mail for remote triggered delivery option is located on the Delivery Options tab of the SMTP Connector Name Properties dialog box.
  • The bridgehead server for the SMTP connector is moved to a different server.
This issue occurs because the domain configuration table (DCT) that resides in memory on the original SMTP bridgehead server is not updated. By "original SMTP bridgehead server," we mean the server that was configured for the SMTP connector. This is the SMTP connector that did not have the Queue mail for remote triggered delivery option turned on.
WORKAROUND
To work around this issue, stop and then restart the SMTP service on the original bridgehead server that caused the issue. To do this, follow these steps:
  1. Click Start, point to All Programs, point to Administrative Tools, and then click Services.
  2. Right-click Simple Mail Transfer Protocol (SMTP), and then click Stop.
  3. Wait several minutes for Active Directory directory service replication to replicate.
  4. Right-click Simple Mail Transfer Protocol (SMTP), and then click Start.
