SpamSieve on multiple email clients

I use Apple Mail for personal email and Postbox for business. I recently switched email hosts for my business email and I get a lot of junk getting through on Postbox. I keep marking it as junk but it doesn’t seem to be learning.

Recommendations?

Please see Checking the Postbox Setup.

Checked the log. SpamSieve sees it as a false negative. Log below:

That is good in that it means Postbox and SpamSieve are communicating. If you are getting a lot of false negatives, you can send in your log file, and I can make some recommendations for improving the filtering accuracy.
