Not only... But there is a lot of brainless schoolboys who are trying to use just this 'imapd' exploit and (due to the number of them) trojaned a lot of computers over the world. It's amazing but I saw few times the stack of trojans installed one over another. To be correct, there is a lot of _really used_ ways to broke the system. The best (and easiest) was 'imapd' and 'qpopper' exploits (you simple run scanner and it detects this services, then you run exploit and it reports _you are root, go on_, then you ftp 'lrk3' or 'lrkb' or 'root_toolkit' and install it. Other way is to use sniffered accounts for the user access, and they you have a lot of exploits to get root; the most popular are 'lprm' and 'X11' exploits for linux, loadmodule and ufsrestore for Solaris and SunOS. If you had not this security holes, it does not mean you was broken, but your chance to be brocen decreases from 30% (for linux with IMAPD) to 1 - 2 % (for other holes). I am not sure about BIND but I saw bind scanning and some logs looked like: ns.xxx.yyy volurentable .... ns.zz.ww not volurentable and I suspect someone have tried to use BIND's bugs too.
