Here is an update to the mail rule utilities I wrote for Notes 8.0. The tool is updated with some minor bug fixes and uses the new Notes 8.5 Widget deployment model. You can check out the original article to learn about its function. The full source is included in the installed jar.
We use Lotus Notes mail as the primary client for POP3 and SMTP mail at home, and the one functionality missing is mail rules. As you know, the mail rules in Lotus Notes run on the SMTP server, and you do not have mail sorting without the Domino SMTP server. Although this tool is not perfect, it does show how to use Eclipse to extend Lotus Notes and to use the Lotus Notes Java backend classes for accessing and manipulating Lotus Notes data.
The tool installs as a new icon in your mail views:
