read slashdot.org... there is a link to an article there about this. Basically there was an advisory out on this. You should be safe if you have the latest version of imapd running. There was a furor over qpopper a while back but I didn't follow it since we don't use it here.
Get the latest version of imapd at ftp.cac.washington.edu:/imap You can figure out what version you are running by just running imapd at the command line. The latest stable version is v11.241.
