For the last few weeks, all emails received from WordTips, Windows Tips, and Ask Leo have had [SPAM] at the front of the Subject line. Checking my ISP's server shows that [SPAM] must have been added on my PC, as it is not present on the server. Clicking "Mark as not Spam" in the McAfee Anti-Spam tab removes it, which suggests it was McAfee Total Protection that was responsible in the first place. The emails were not placed in the McAfee Anti-Spam folder - I assumed this was because the Rules I have set up took priority.
However, today I received an email from Ask Leo which WAS moved to the McAfee Anti-Spam folder. So when I clicked "Mark as not Spam", it was moved to my Inbox and I had to move it to my chosen folder manually. This has turned it from a mild irritation to an annoyance.
What can be causing this and is there anything I can do to stop it?
