***This is just a message to those of you out there that use the SMTP service from Microsoft.***
The creator of the five-ten lists is creating another section of those lists. It involves one, that after some research, has been la larger source of spam recently. The new section will hold IPs for Microsoft Windows 2000 and 2003 servers that run the SMTP service and have the Guest account enabled with the default password. If the Guest Account password is not changed, the SMTP service can be hijacked with one script and about 10 seconds. They have started cataloging servers that fall under this criteria. Just an FYI.
