If your list is open, or uses a restrict_post that does not point
to the list itself, majordomo can process a message to a list this
size in seconds even on a low end machine.  

The issue becomes one of how fast can sendmail or other MTA process 
a message with 50K recipients in the envelope through the queue?  

There are dependencies on bandwidth, CPU, DNS, and the speed of 
connection and CPU on the other end as well.  If you break up the 
envelope into smaller groups of addresses creating many copies of
the same message for delivery, you put dependencies on IO and 
disk/temp storage, but the queue can be processed in parallel 
instead of serially.
