--------------------------------
Status: Patch Available (was: Open)
> ConsumePOP3 and ConsumeIMAP do NOT delete messages
> --------------------------------------------------
>
> Key: NIFI-3976
> URL: https://issues.apache.org/jira/browse/NIFI-3976
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.0.0
> Reporter: Koji Kawamura
> Assignee: Koji Kawamura
>
> Those processors have 'Delete Messages' property but even if user configured
> it to 'true' messages are not deleted from mail server.
> AbstractEmailProcessor which is a superclass for both processors, has been
> using:
> {code}
> emailMessage.setFlag(Flags.Flag.DELETED, this.shouldSetDeleteFlag);
> {code}
> However, since we are using Spring mail, the underlying receiver does not
> close the inbox connection so messages are not deleted.
> Instead, we should use:
> {code}
> receiver.setShouldDeleteMessages(boolean)
> {code}
> To specify whether it should delete fetched messages or not.
