for information regarding the largest size lists that have been known 
to run Mailman.

	Everything is going to be dependant on your hardware, OS, 
software configuration, etc....

	It is entirely possible to run lists of this size on remarkably 
low-end hardware, if you've gotten the configuration correct.  Or, 
you could have major problems on a high-end machine, if the system is 
not configured correctly.  It all depends on what you've got and how 
you use it.

	I recommend you search the FAQ for terms like "performance" and 
"VERP", and read all of the entries that are found.

	You may also want to search the postfix documentation, and read 
their pages regarding performance tuning, etc....
