We use amavisd-new here on several servers for several different
non-profit entities, and it has perfomed reasonably well. It's written in
perl and perl is interpreted (well, byte code, I believe). So, you can't
expect it to be the fastest thing around. However, it does a good job at
preforking processes and keeping that part of the processing low. I agree
with your last statement above. We have nowhere near the insane amounts
of email (right now) that some people on this list pump through. I'm sure
the performance curve would level off as the amount of email rises. For
now, it serves us pretty well.

I would mostly agree with your observation, but I would add to it that if
there is a guru available for whatever you are doing (Linux, postfix,
amavis, etc.), you tend to be much better off. They spend less time
fixing whatever problems pop up. A less experienced/knowledgeable person
would require much more time to fix a problem, and because they might not
really understand what they are doing, the problem could become chronic or
cause other problems. So, the company either winds up paying for
expertise or a quality product.

If I may summarize the rest of what you wrote, you get what you pay for.
Either it comes out of someone's time, or it is invested in a product that
provides the convenience and features you need.
