Don't see this in the usual repos, but I do see the epel repo has something called "uw-imap-utils," which seem to date to 2007. I'll take a look at both. -- Tim Evans | 5 Chestnut Court UNIX System Admin Consulting | Owings Mills, MD 21117 http://www.tkevans.com/ | 443-394-3864 tkevans at tkevans.com
