### Integration with Web feeds ¶

RSS and Atom feeds could be collected using rss2email program. It converts all incoming feed entries to email messages. Read about how to integrate Integration with Postfix/Integration with Exim with email. `rss2email` could be run in a cron, to collect feeds without any user interaction. Also this program supports ETags and won’t pollute the channel if remote server supports them too.

After installing `rss2email`, create configuration file:

    $ r2e new rss-robot@address.com

and add feeds you want to retrieve:

    $ r2e add http://www.nncpgo.org/download/releases.atom

and run the process:

    $ r2e run

But it is more flexible and advisable to use use feeder (NNCP’s author creation) that also transforms feed entries to Maildir email messages. Incoming entries are placed in `new/` Maildir directories, so you can easily send all of them:

    % tar cf - **/new/*(.) | zstdmt | nncp-file - remote.node:feeds-`date -Iseconds`.tar.zst
    % feeder/dir/contrib/feeds-oldenize.zsh

Unlike `r2e`, `feeder` has also enclosures and WARCs downloading capabilities, that are also stored as a files on the disk.
