General
This plugin extends Jenkins built in email notification functionality by giving you more control. It provides customization of 3 areas.
- Triggers - Select the conditions that should cause an email notification to be sent.
- Content - Specify the content of each triggered email's subject and body.
- Recipients - Specify who should receive an email when it is triggered.
Configuration
Global configuration
Before using email-ext on a project, you must configure some global settings. Go to Jenkins System configuration page. Manage Jenkins -> Configure System
The section titled Extended E-mail Notification is where you can configure global email-ext properties. The properties here should match the settings for your smtp mail server. This section is set up to mirror Jenkins own email Publisher Reporter (It's different extension point), however there are a few additions. The inputs labeled Default Subject and Default Content, allow you to configure the email content on a global level. The input labeled Default Recipients can be used to set a default list of email addresses for all projects using plugin (it can be overridden at the project level). This can be used to greatly simplify the configuration you need to do for all projects.
在全局配置中，section名字为Extended E-mail Notification。其中配置recipients的配置，
Customize the default recipient list of the email notifications. The plugin will use this list if none is overridden in the project configuration. You may use the $DEFAULT_RECIPIENTS token in projects to include this default list, as well as add new addresses at the project level. To CC or BCC someone instead of putting them in the To list, add cc: or bcc: before the email address (e.g., cc:someone@example.com, bcc:bob@example.com).
