Hmm... I wouldn't think Hotmail would portscan unrelated IPs to find SMTP
relays on wierd ports. Or did Hotmail turn into an ISP when I wasn't watching?
It's just wierdly coordinated - all these different IPs within the same ARIN
block 64.0.0 - 64.4.63.255 looking at random ports. Dshield hasn't recognized
any IPs I've fed it so I'm not sure what to make of it. I might just phone
the contact for the ARIN block at Hotmail and see if he knows what's going on.
