It would automatically be saved to a static file periodically, for mirroring to the static front end servers. Using an imap source shouldn't be a major problem, but how would you expire messages?

Hmm, Firefox doesn't like that very much, perhaps because it's being served as text/html not application/rss+xml: http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fsraapowergres.com%2F en%2Fnewsfeed%2F Regards, Dave.

Excellent idea. We could add tags of our own into the email news event that when read by the script would also carry out extra instructions. For example, if there's an older announcement that is still important it could still be placed near the top of the list by using one the RSS ordering tags on the news items. regards Robert
This is an interesting way to set up feeds. We could the same with our own mails lists if we wanted to: http://www.newscientist.com/feeds.ns cheers Robert
