Bah, excuse the poor english in the topic. I changed thoughts half way though composing and didn't proof the subject!
I have a user who has reported curious behavior to me. He has a filter set up in ZWC to push a lot of internal automated email to a folder. He noticed recently that there are times where email that is usually caught by the filter slips through into his inbox.
The was about the time I upgraded to 6.0.9 and it continues in 6.0.10. He didn't recognize the pattern till now so I can't be sure when it started.
I'm curious if the filtering engine turns off during periods of high load to allow zimbra to keep delivering email? I ask because I've been noticing that this server is getting towards capacity and it's load does have spikes. If the filterning engine does not turn off for load, then this is a bug that was probably introduced in 6.0.9.
Any insight is appreciated.
