message caught by SpanSieve - marke not junk - then returns to junk folder -- Huh??

running 2.9.17 using PostBox 3.0.11, on MBP Mavericks 10.9.5
I marked a message as not junk. It goes to the inbox, but about 5 seconds later it returns to the junk folder…what is going on? thanks

You could check SpamSieve’s log to confirm whether this was because of SpamSieve. My guess is that it was moved by a server filter or a mail client’s rules on another Mac.
