RSS2EMail

This program checks subscribed RSS or Atom feeds and emails every story it has not seen before. It creates a configuration file and feed database with `r2e new`, then records seen items for each feed in a JSON data file. Subscriptions are added with `r2e add`; on the first run, `r2e run –no-send` skips sending existing stories. Delivery uses local sendmail by default or SMTP with authentication and TLS options. Messages can use configurable HTML instead of plain-text conversion, adopt the item’s posting time in the Date header, and report every post change when `trust-guid` is enabled.

It is for people who want feed updates delivered to their email inbox, including users who prefer local sendmail and those who need direct SMTP delivery. Custom configuration and data paths accommodate users who do not want the default file locations, while `force-from` can address “Sender domain must exist” errors.
