Well, listar.org runs Postfix. :) (Unfortunately, the primary data drive
for listar.org died on Wednesday, and is at a data recovery house right
now. *sigh* The Listar.org lists will be back soon, though. A week,
probably.)

Beyond that...? I have personally run Listar lists up to 70,000 users,
though that was on Sendmail + smtpfeed, not Postfix. My only bad
experience with massive mailing under Postfix is a simple one... I get
ident request flooded. :) So I tweaked my local Postfix settings to delay
a little bit between queue chunks, so I don't see 6800% CPU usage just
from things doing identd for mail connections. ;)

I hope that helps! If you have Listar/Postfix questions, feel free to ask
me directly while listar.org is down.
