I guess you'd better define "relatively common hardware". What are we
talking about here? Some benchmarking I did of real-world recpieints
has shown that a dual PII 450 with a GB of RAM and the mail spool set
up on a 500MB RAM disc, and upstream connectivity of dual DS3s,
was able to handle around 100k deliveries an hour. This was using
qmail with a remote concurrency of 250 and a bunch of little tricks.
So, unless I missed something pretty serious in the configuration
of this environment, "relatively common hardware" should include
at least a dozen boxes.
Again, this was a real-world list of around 400k addresses of users
who had signed up to receive a particular announcement. They have
since moved to a cluster of around 10 machines running some custom
software and are getting over 1M per hour with that setup.

I could probably donate 5% to 10% of that amount across a few upstream
What exactly would a "free, no-risk trial" of an on-line casino be?
