For instance, last night:

Checking for rejected mail hosts:
   7 k12coffee.net
   3 e-standard.biz
   2 yahoo.co.kr
   2 positive-id.biz
   2 eu-vest.biz
   1 tgflk.com
   1 schmidtbank.de
   1 repairnet.biz
   1 funeasy.biz
   1 edenbs.demon.co.uk
   1 drop-bear.com
   1 caracha.net
   1 admin.darcoinc.us

These levels are actually pretty low, because I know my cable ISP (Time
Warner) is blocking some of the worse scanners at the network border.  I'd
see a large number of probing attempts on whatever ports were available -
FTP, SSH, whatever.  Most of the exploits are for Windows vulnerabilities,
but not all.
