Hi
I would like to know the MAX values listed below for mailman2. Is there any document that explains them?
Is there a limit to the number of mailing lists that can be created in mailman2? What is the maximum number of recipients that can be registered to a single mailing list created by mailman2?

There is no limit for maximum number of mailing lists. You need enough disk space for settings and archives on your system. And your system has to be able to cope with the traffic.
There is no limit for maximum members of one list. It all depends on your system and its network capabilities. As long as you have enough network bandwidth for sending to those members in a timely fashion everything is well.
Kind regards, Christian Mack

The best place to look for Mailman2 answers is wiki.list.org. Such as:

See the above link. It describes a number of cases of lagre Mailman2 deployments.
There are no arbitrarily-imposed limits on the number of lists or the number of users per list. You can run into serious performance problems as the number of list members increases, due to the way Python 'pickle' files are used. If you throw enough memory, fast enough storage, and enough cpu cores at Mailman, it can scale to hundreds of thousands of users and hundreds of lists, but you may not be pleased with the resources required to get good performance at scale.
Mailman is designed for discussion lists more than it is for high-volume announcement/marketing lists. It takes significant MTA and backend tuning to mail more than a few thousand users in a reasonable amount of time, and Mailman is not always the right choice for that.
