I'm having the same problem with a godaddy hosted account we send to ... they claim we are using an IP address that we don't use and have us blocked. No answer yet ... we've been working with them for over a month now.

If I telnet to that .2 address on ports 25 or 110 nothing appears to be there Any suggestions on why this might be occuring, what it means and what I should look at to address it? Thanks !!!
