In the last week, several emails to failed to be delivered. The error message is "522: email sent from <IP ADDRESS> found on industry IP blacklists". The IP ADDRESSES were 777.238.176.54, 777.238.176.244, 777.238.177.61 and 777.238.177.110. I use Yahoo email on Windows 7 on Virgin Broadband. Other emails appear to be OK. I am concerned that something seems to be using an Industry blacked device on the email route between Virgin, Yahoo and BTinternet. I phoned Virgin technical services (not UK based), only to be told that Virgin do not have a Security Section for investigating potential security breaches!

Please help.

I didn't find the right solution from the Internet.
