Actually, Brad Knowles' answer was quite good.

A day has 24 hours. Each hour has 60 minutes. Each minute has 60
seconds. That makes for a total of 86400 seconds per day.That means
that you had to send out about 2 mails per second. Given a setting of
SMTP_MAX_RCPTS of 500, that means that mailman would deliver about 200
mails to your MTA - non personalized, non VERP'ed. This is not a
problem at all from an MTA's point of view (perhaps somebody with more
knowledge of Mailman can, again, say something about Mailman's memory
requirements with that many recipients). Even with default
configurations and a rather poor DNS cache, I can't see a problem with

Now, you still have to do bounce processing - which again, with 100000
recipients, shouldn't be that much of a problem.

So given that you have a non-personalized list, don't do VERP, I'd
say: Go for it.

If you need personalization or need to do VERP in Mailman: I'd say
forget it.

Now if you want a more educated answer, review what Brad said.

Mailmans installation manual http://www.list.org/mailman-install/index.html
is one of the most detailed and easy to understand writings I have ever seen.
