Introduction

The JITL MailInboxJob template can be used to create a job that reads a mail inbox.

  • The job template makes use of the IMAP or POP3 protocol to read mail.
  • The job template can be used to specify settings from different sources:
    • Connection Settings
      • This includes settings such as the IMAP/POP3 host, port etc.
      • It is recommended to use JS7 - Job Resources for this purpose as such settings suggest to use the same values for any mail inbox that should be read from the same mail server.
    • Mail Settings
      • Such settings are specific for individual mail inboxes and include e.g. the folder of the mail inbox.
  • The job template can be used with a JS7 - Credential Store.
  • FEATURE AVAILABILITY STARTING FROM RELEASE 2.1.1

Usage

When defining the job consider

  • to invoke the Wizard that is available from the Job Properties tab in the Configuration view and to select the JITL MailInboxJob and respective arguments from the Wizard

or

  • to specify the JITL job class and com.sos.jitl.jobs.mail.MailInboxJob Java class name, then add arguments what to send and where to send mail as explained from the below documentation.

Example

Download: jitlMailInboxJob_sample.workflow.json

You can use the job wizard like this:


Explanation:

  • Add an empty job from the instruction panel.
  • Specify a name and a label for the job.
  • Select an Agent.

In a next step invoke the job wizard that you find in the upper right corner of the Job Property editor. The wizard brings up the following popup window:


Explanation:

  • From the list of available job templates select the MailInboxJob.

Then hit the "Next" button to make the job wizard display available arguments:


Explanation:

  • Required arguments include the mail.store.protocol argument to specify imap or pop3 to be used.
  • Any other arguments are optional provided that a Job Resource is used that specifies connection details to the mail server, see below. Otherwise individual settings such as the IMAP/POP3 host, IMAP/POP3 port etc. have to be specified from arguments.
  • When using a secure SSL connection consider to
    • use the mail.imap.ssl.enable argument with the value true,
    • optionally use the mail.imap.ssl.protocols argument with a value such as TLSv1.2 or TLSv1.1,TLSv1.2 to specify one or more protocol versions that limit handshake with the mail server to the specified protocol versions. Depending on the Java version in use and possible modifications of the java.security file a number of protocols could be enabled that might not match the mail server's capabilities. Typically SSL handshaking starts from the highest protocol version accepted by both parties, however, it is not guaranteed that protocol negotiation will perfectly work. In such a situation it is recommended to specify the protocol version by use of this argument.
  • Select the check box provided with each argument if you want this argument to be added to the arguments of the MailInboxJob.

When hitting the "Submit" button the wizard adds the required arguments to your job that should look like this:


The job arguments can be specified

  • from individual variables as offered by the job wizard.
  • by use of Job Resources.

Use of Job Resources for Mail Settings

A number of settings for reading mail inboxes most probably carry the same values when used for different mail inbox jobs. This includes e.g. use of the IMAP/POP3 host, port etc.

  • You can specify such settings individually from variables that are assigned the job's arguments, see above.
  • You can specify such settings from JS7 - Job Resources that can be re-used for any number of mail inbox jobs.

Setting up a Job Resource for Mail Settings

You can create a Job Resource that includes settings required to read mail inboxes.

A Job Resource has two sides, one being the variables that are specified from the "Arguments" sub-tab and the second is about "Environment Variables" that are available for Shell Jobs. For the purpose of use with the MailInboxJob it is sufficient to specify variables from the "Arguments" tab.


Explanation:

Assigning a Job Resource for Mail Settings

A Job Resource can be created, deployed and assigned the MailInboxJob to populate the job's arguments from the Job Resource like this:

The MailInboxJob can be used with a credential store to hold sensitive arguments. For use of the credential_store_* arguments see JS7 - Use of Credential Store with JITL Jobs.
