How To Perform A Meaningful SMTP Telnet Test To Troubleshoot Java Mailer For Sending Email Notifications (Doc ID 753845.1)

Oracle Workflow - Version 11.5.9 to 12.2 [Release 11.5 to 12.2]
Information in this document applies to any platform.


This document details the steps to perform a meaningful telnet test to investigate java mailer issues related to sending workflow email notifications to the SMTP server.

As it is explained in the Oracle Workflow Administrator’s Guide, it is mandatory to have an SMTP server set up in order to send the workflow notification e-mail messages. This means that the notification mailer does not send the notification e-mails itself but completely relies on the SMTP server to achieve this task.

For this reason, it is important to be able to send an email using telnet on the SMTP server in the conditions that are used by the mailer.

Note: this test is useful in the following situations (the below list is not exhaustive):

- One is setting the workflow notification mailer up and wants to validate the outbound processing parameters.
- One is suspect of a connectivity issue between the java mailer node and the SMTP server node.
- One suspects that the SMTP server does not process emails.
- One wants to validate a given email address.

More particularly this test will provide relevant output when the following strings are seen in mailer log:

- javax.mail.SendFailedException: 550 5.7.1 Unable to relay
- javax.mail.MessagingException
- Invalid Address
- Relay access denied
- Unable to relay
- Relaying denied
- Client does not have permission to submit mail to this server
- Validation failed for the following parameters -> {OUTBOUND_SERVER=Unable to make a network connection.}
- EXCEPTION:[SVC-GSM-WFMLRSVC-12848-10006 :]:Not sending notification {3939936}because the notification mail status is null OR not 'MAIL'
- Updating notification {3939936} status {FAILED} {WFMLRSND_FAILED_UNDELIVERABLE} {{SYSADMIN}}...
