Yes... I actually run a newsletter that has 240,000 subscribers. Depending
on the machine you are running this on, there are some issues with LARGE
lists. One seems to be that mailman *appears* to load the entire config DB
when you attempt to modify anything. This means a VERY large python process
that tends to be rather slow. I am using dual PIII 650MHz boxes and it was
quite painful. What I would suggest is setting up an umbrella list, that
feeds several smaller lists. It's not too hard to manage, and improves
performance dramatically. I try to limit my mailman lists to 25,000
members. It can handle about 40,000... but you begin to push the boundry of
useability.

Hi
Our institution is a university. We are using mailman for distribute
messages for some disciplines and institutes, but now there will be
necessity to distribute informations for all students. We thinking
about create a list for distribute this informations for everybody -
more or less 40.000.
My question: are there anyone using a mailman list with this size?
Are there known problems or possibilities?
Thanks in advance
