All Implemented Interfaces:

MonitoringStrategy

public class Pop3PollingMonitoringStrategy
extends PollingMonitoringStrategy

Implementation of the MonitoringStrategy interface that uses a simple polling mechanism suitable for POP3 servers. Since POP3 does not have a native mechanism to determine which messages are "new", this implementation simply retrieves all messages in the Folder, and delete them afterwards. All messages in the POP3 mailbox are therefore, by definition, new.

Setting the deleteMessages property is therefore ignored: messages are always deleted.

Since:

1.5.0
