NewsPipe? setup

NewsPipe is an RSS/Atom aggregator that collects new feed items and converts them to e-mail messages, which you receive with your mail reader. NewsPipe users can definitely benefit from the immediacy of FeedTree delivery: you'll receive emails as soon as new feed entries are posted.

Configuration

In your newspipe.ini file, add a proxy line:

proxy=http://127.0.0.1:8501/

That's all you need to do, though to be sure NewsPipe picks up the FeedTree-delivered items as soon as possible, you'll want to adjust the delay property of each of your feeds (set delay=10 for each feed in your OPML file).
