> Key: JAMES-2279
> URL: https://issues.apache.org/jira/browse/JAMES-2279
> Project: James Server
> Issue Type: New Feature
> Components: Mailet Contributions
> Affects Versions: master
> Reporter: Tellier Benoit
> Priority: Major
> Labels: easyfix, feature, newbie
>
> James mail queues is handling mail priorities. See the *MailPrioritySupport* interface.
> This is done using the MAIL_PRIORITY mail attribute. It is an integer property ranging from 0 (low) to 9 (high) and mail queue component will default to 5.
> Today, the mail processing unit akka mailetContainer can not change the priority set by the SMTP layer (using *MailPriorityHandler*). This is a problem as we can not re-prioritise outgoing emails, for instance in remote delivery queues.
> I would thus propose the following mailet:
> {code:xml}
> <mailet matcher="All" class="WithPriority">
> <value>8</value>
> </mailet>
> {code}
> Furthermore, we might want to customize processing logic depending on the priority (might it just be for debugging purpose).
> To do so, I propose to introduce the following matchers:
> {code:xml}
> <mailet matcher="HasPriority=8" class="Any"/>
> <mailet matcher="AtLeastPriority=8" class="Any"/>
> <mailet matcher="AtMostPriority=8" class="Any"/>
> {code}
> *How to do this?*
> In the `server/mailet/mailets` project, in the mailet package create the WithPriority mailet which sets the MAIL_PRIORITY attribute.
> Create the matchers in `server/mailet/mailets` in the matcher package.
> Write unit tests for these mailets / matchers.
> Use MailetUtil content to parse the integer conditions/value. You can reuse https://github.com/linagora/james-project/pull/1215 to ease your work.
