I have list set up that I want to send a newsletter out to. The Iist is about 50000 addresses.

Will Mailman and sendmail be able to handle that?

It all depends on the system setup. With a good portion of RAM, a clear connection, and quick access to a DNS server, it should be fairly smooth.

A local DNS server will speed things up.

Also how are the emails sent out when I click send? Is the entire list spooled and then sent out or does it do it in chunks -

This process is handled by the MTA. mailman hands off the mail to sendmail and then sendmail processes the queue, usually host at a time. Which means if one host isnt' resolving, the rest of the queue will have to wait til that host timesout.
