Hi there,

As of 2 days ago, Norton (NIS 2011) has been popping up repeated error messages reporting email errors. As soon as I close one a new one pops up. None of them relate to my email address, or any activity that I am doing myself. There are a few variants:

- 550-506.1 [] The IP you're using to send email is not authorised to
- Your email message was unable to be sent because the connection to your mail server was interrupted. Please open your email client and re-send the message from the Sent Messages folder
- 451 Message temporarily deferred - [70]

and some more variations along these lines.

I've run full scans with Norton and Malawarebytes, with no results showing. I'm using XP. I assume that I have some malware which is attempting to use my system to route spam, but I'm not sure how to tackle it. Any advice would be very much appreciated :)

I have the same problem for 1 week. Same OS and same Norton version.

Norton and Malawarebytes not solve this. After many tests I keep looking but can not find the solution. Any ideas?
thank you very much

Hi Demiguelj,

To update my post, I downloaded Superantispyware and ran a scan with Norton disabled in case Norton prevented the other software from accessing registry items etc. Superantispyware found several tracking cookies, and one trojan (which I think was a false positive but removed anyway.)

I then ran Malwarebytes again (still with Norton disabled, same reason as above), which then reported three more trojans and two riskware items, which I quarantined.

Then I ran a full Norton scan, which again came back clean.

By the way, I was disconnected from the internet while Norton was disabled.

Since then I haven't experienced any problems, but would still appreciate it if someone could advise or check a log to be sure that my pc is clean. I would also be interested to know how I picked up the malware, to prevent the same issue arising again.

I hope that helps you, demiguelj, or anyone else with the same issue.
