I’m running a trial of SpamSieve on Apple Mail 6.6 (pre-Maverick). So far so good, it’s catching almost every new spam each morning.
In the past, I spent time each day junking and deleting ALL spam on all my email addresses. AFAIK, there is NO spam in my existing InBoxes. They are very clean. I also file many messages into subfolders On My Mac when archiving.
The only problem I’m finding is that when SpamSieve learns a little more, it seems to scour my old Sent Inbox - which has emails from 2011-2013. It then moves dozens of them to its own “spam” folder and changes them to Unread. (There’s nothing spammy about my replies!)
To try to twart this behaviour, I moved all my previous Sent messages to a new folder On My Mac. I assume that SpamSieve will NOT search thru messages On My Mac? (I hope this is tru, because these are carefully sorted into many different subfolders.)
Feature request: Would like a preference to “Only Scan New /Unread Messages”, so that it doesn’t waste time scanning existing Inboxes & Sent inbox for spam as it will only find good messages to move to its spam folder.
