Background: I'm writing a few pieces on teergrubing, an anti-spam
defense. The question isn't strictly GNU/Linux related, though the
GNU/Linux case is useful.
I'm curious as to the typical, high-end, and theoretical maximum number
of outbound mail connections which can be maintained by a server. I'm
assuming a relatively standard network stack, e.g.: GNU/Linux, BSD, or
legacy MS Windows, all of which I understand use the same fundamental
BSD stack anyway.
From my own experience with mailer configurations, typical outbound
concurrencies tend to be in the range of low double-digits -- say, 10 -
40 outbound. And the network stack is limited to a maximum of 65,535
ports (right?). So, a high-end mailserver would have how many outbound
connections? I'm thinking specialized spamware here.

What Part of "Gestalt" don't you understand?
A few years ago you could buy a CD, knowing that it was a standard
product... Now, you...find that you can play it in your hi-fi, but
not in your car. Next time, you're not going to make that mistake,
you'll just log on to Kazaa and download an MP3.
