El Captain Problem: Spam Messages Marked But Not Moved

I have been having the same experience after my El Capitan install. SpamSieve will properly identify and mark messages as spam (i’m color coding them) but will randomly stop moving them to the identified spam folders. Training an individual spam message works fine and does move them to proper folder. Here’s the latest console errors I’m seeing:

10/19/15 12:12:49.000 PM kernel[0]: SpamSieve[75227] triggered unnest of range 0x7fff93800000->0x7fff93a00000 of DYLD shared region in VM map 0x910375b376ad1885. While not abnormal for debuggers, this increases system memory footprint until the target exits.

This does not sound like the same problem to me, because the original poster said that the spam messages were not marked. Please update to the latest public beta version (2.9.22b2) and also see the Why are messages marked as spam in Apple Mail but not moved? page. If you still see the problem, please contact me via e-mail with your Console log.

I did not hear back from the original poster, and this looks like an issue that was resolved in SpamSieve 2.9.23.
