Postfix queue fulling up

[UxBoD]

FuzzyOCR uses quite a lot of RAM aswell.  Have you configured it so that it will not process images if the SA score is already greater than your threshold ?

1GB of RAM is pretty low to be honest.  Instead of a second processor, IMHO I was add at least another 1GB of RAM. At work we process 150k messages per day and I got them to buy a new server with two dual core Opterons and 8GB of RAM.  Okay, this sounds over-spec'd but we have a lot of SA rules and plugins and never ever have a queue.

Regards,
