I upgraded from 4.0.3 to 4.5 last night, and found this morning that a _ton_ of spam was getting through. Comparing headers I noticed that the new spam doesn't have any of the X-DSPAM-* stuff, and then I found this in my zimbra.log:
Jan 17 20:00:57 zimbra amavis: No $dspam, not using it
Is this an intentional change? What should I be doing to catch spam now, since it seems the dspam was doing most of the heavy lifting before! I'm going to turn it back on and see if that helps make people's inboxes usable again, but I'd love to know if others have experienced this (the major increase in spam, and/or the dspam disabling).
