First of all, has anyone else noticed a strong spike in spam scores since the new year?

 

Secondly, we've noticed that even internal messages from myself to a co-worker are ending up in the junk mail folder in webmail.  It almost seems to be content related.  I sent one message to him with a subject of 'test' and it went to his inbox.  I sent a second with a subject of 'spam' and it went to junk.  Sent a third with a subject of 'spam 2' and it also went to junk.

Declude logs (set temporarily to debug level) shows exactly what it should:

01/15/2015 14:53:44.653 229367178 Skipping E-mail from authenticated user jerry@nicsys.net; whitelisted.
01/15/2015 14:53:44.653 229367178 Past whitelisting
01/15/2015 14:53:44.653 229367178 E-mail whitelisted - automatically passing all spam tests [Authenticated; jerry@nicsys.net]

Then Smartermail logs seem to show the same:

14:53:45 [67178] Delivery started for jerry@nicsys.net at 2:53:45 PM
14:54:01 [67178] Skipping spam checks: User authenticated

14:54:04 [67178] Delivery finished for jerry@nicsys.net at 2:54:04 PM    [id:x229367178]

That Filter: None supposedly means no filters were applied to the message, which means it should have ended up in the inbox, but it clearly did not.  I've checked his personal content filtering and the domain content filtering.  There's nothing there, so...what gives?  Any help would be appreciated.  If there's more info I can provide that would help, please let me know.  Thanks.
