There seems to be some confusion on how to report spam/phishing emails or those containing a virus to TalkTalk.
On page http://help2.talktalk.co.uk/guided-assist/report-phishing-or-spam-email/outlook-2010-2013/ we are asked to cut and paste the email headers into a new email to either phishing@talktalk.co.uk or spam@talktalk.co.uk as appropriate.
However at http://help2.talktalk.co.uk/phishing-scams we are asked to first save the suspect email to our own computer, create a new email and then attach the saved suspect email to that.
I have always used the cut and paste method, after which I receive an automated acknowledgement - which asks for the header details once more, though perhaps this is standard as the system cannot recognise what has been sent and just sends a generic response.
I may be sending too much information initially - before I download emails into Outlook 2013 I filter everything using Mailwasher, so cannot use the method you quote to isolate and copy the headers. Mailwasher does allow me to view the suspect email in plaintext form however which should achieve the same result. I am extremely loathe to actually download the email, as there is then a chance that the email could be opened accidentally and any payload deployed. I have had to deal with the fallout when several friends did just that!!
However, I do not get any further contact, and am unsure if this is because the system expects a response from me so eventually closes the case or if no further contact is actually needed.
I do recall that in the past I was copied in on your report email to the sending isp, but that hasn't happened for some time.
I look forward to reading any comments and have temporarily stopped my reports pending clarification of which method that I should use.
