	There are no hard-coded limits.  There are certainly going to be 
practical limits.  What those practical limits are will depend on 
your hardware configuration, your OS, etc....

	Mailman will send out as many messages per hour as it can, 
depending on the limitations of your hardware, OS, software, etc....

	A real Customer Relations Management system.  See
