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.

even running bind 8.1.2?

Yes, if, as his message continued in the part deleted, you are running
an unpatched imapd on the same machine.
