You're at 81.108.73.221, and using NTL's mail servers too!
... so I assume you're just blocking inbound connections? If you'd nullrouted 
the whole shebang you'd have chopped off your own legs :)

I've said it before; I'll say it again: switch off logging. You *know* it'll 
generate massive files. If I'm running real services, I watch them instead. 
If I've nothing to offer on a specific port then I don't give a flying one who 
pokes it, because there's nothing there.
