I have a similar problem that actually is related to SpamSieve, in that no matter how often I mark a promotional newsletter as “good”, all but one of emails that arrive in one day invariably shunt into spam. There are others that don’t arrive more than once a day, including one from USPS, that also ends up there more often than not.
Can I make an uneducated guess that the screening system is set up to automatically reject any address that appears more than once or twice in a 24-hour period? Can I also say it’s rather annoying?
How do you know that it’s related to SpamSieve? Does SpamSieve’s Log window say that it predicted those messages to be spam?
That’s not how it works at all. In fact, when you train a message as good SpamSieve will not move any more messages from that sender to the Junk mailbox (unless you also train them as spam). So, based on what you’ve written, it sounds like something other than SpamSieve is moving those good messages.
