ORA-29278: SMTP transient error: string tips

Oracle Error Tips by Burleson Consulting


The oerr utility notes this on the ORA-29278 error:

ORA-29278: SMTP transient error: string

Cause: A SMTP transient error occurred.

Correct the error and retry the SMTP operation.

The ORA-29278 error may signify that, the same server where you have your Oracle database running, does not have an SMTP server up and running.

This solution can help to resolve ORA-29278 errors:

Go to Control Panel->
   Add or Remove Programs->
      Click on Add/Remove Windows Components

Check IIS check box.

Select Internet Information Service (IIS) option and click on Details button

Check whether SMTP Service is checked or not.

If not selected then select SMTP check box.

This process should be done on server.  It will help out from ORA-29278: SMTP transient error: 421 Service not available problem.

Shutdown any applications that are blocking or preventing use of the port, 25, required by UTL_SMTP." because the cause of the error may be associated with other applications (like anti-virus utilities), "blocking access to the port required for UTL_SMTP.
