I don't get a massive amount of spam mail but today found one which appeared to come from my own email account. Normally I just select such messages then block the senders but on this occasion the 'block all mail from...' confirmation message opened up showing my own email address listed as opposed to the sender's. I know that often the displayed email address on such messages is false with the real sender being revealed when I view the message source. On this occasion I'm confused about why my address is shown on the to be blocked list.
Can anyone clarify please? TIA as always.
