Ergo, any trust infected was still running it's own improperly configured separate mail system in preference to using the centrally provided NHS Mail system (nhs.net)
I'm not sure that this actually came in by mail. There was an IBM guy on Radio 4 this morning saying that they'd scanned a billion (literally) mails and hadn't found any with the original infection. Is the source for the mail infection angle just one statement from Telefonica?
