The site where I work is considering replacing our current listprocessor (ListProc 6.0c) with either Mailman or Majordomo. So I was going to as a benchmarking type question, what sort of a system would be required to run 100 lists each sending out 100 emails a day? Obviously a 486 /can/ do it, but reasonibly fast sending is nice. (ie would something like a pentium2 250 with 128 RAM be enough)
It's going to depend on things like how big each message is, how much delay there is caused by slow recipient systems, how fast your disk drives are, what kind of file system you're using, etc....
I'd recommend a fair amount of RAM (256-512MB), but beyond that spend as much money as you can on getting the fastest disk subsystem you can (at least a separate disk for the /var/spool/mail filesystem, and possibly mirrored+striped), with the fastest filesystem (well, fastest filesystem that is safe for your OS).
But even if you had the fastest computer on earth, that would be no guarantee of speed if all your recipients are sending large messages and are located behind slow dial-up lines.
Secondly how long (estimate, please) would it take to send all 10000 emails should they be sent to the lists at the same time?
This depends on even more factors.
Check the FAQ wizard at <http://www.python.org/cgi-bin/faqw-mm.py> and search for things like "performance", "verp", and "largest list". There should be a dozen or more hits for these search terms, and you need to read and understand each of the FAQ entries in question.
