If you use Unix, rss2email will let you subscribe to a list of news feeds by email, so that whenever a new update is posted, you get an email message with the full text (it even renders HTML for you!).
Version 2.0 is better, faster, easier, and more reliable. It supports GUIDs, Unicode, quoted-printable, and errorReportsTo and more. I’m actively maintaining it, so your feature requests and bugs are often implemented within hours!
Other than that, a Google search for rss2email turned up 309,000 pages. Surely one of them will apply to your flavor of linux.
