What's the problem?
When using standard mail handler all newly created users get into jira-core group, so that they consume the license. This is not the best way to use JIRA licenses when you have a lot of external users which are not supposed to log into JIRA.
Installing Helpdesk Mail Handler
After installing Helpdesk plugin a new Helpdesk Mail Handler will appear.
This mail handler is based on Atlassian 'Create a new issue or add a comment to an existing issue' mail handler. It has the same features and additionally allows to:
- specify a JIRA user group which all new users will be added to. Thus all new users will not be added into jira-users group and will not consume JIRA license.
- create issues with blank Summary.
Configuring Helpdesk Mail Handler
There is a special parameter to specify a JIRA user group which all new users will be added to - New user group:
Sometimes E-mails contain garbage (trash attachment) files without extensions. These files can clutter Issue Attachments section. Use 'Regexp to filter attachments' to avoid garbage in issue.
^([^.]+)$
To filter all attachments with specific name (for example for JIRA-generated files) use regular expression:
.*[jira-generated|atlassian].*
You can also filter images embedded into text so that they will not be added as an issue attachment. If you select this parameter you can configure image size to be filtered.
If the Handler deletes any attachment from the comment it will inform about it at the end of the comment: "The following attachments were deleted:"
You can save the content of CC field of e-mails in selected custom field (Text or HTML field type).
The examples of other mail handler parameters can be found on Atlassian site.
