freshmeat.net: Project details for imap2rss.php
“imap2rss.php is a program that exports the contents of an IMAP folder as an RSS feed. It reads the folder in real-time and has support for multi-part MIME messages and permalinks.“
OK, so we take the email destined to webmaster and make it a feed. From there we all look at feed and respond to the messages as appropriate.
