This is a host configuration question.  Mailman just sends the post to
the host's mail transfer agent (MTA, such as sendmail, postfix, or
exim).  You need to talk to your system admin about this.

In general, mass mailings of that scale should complete within a
couple of hours from Mailman's point of view, and with the appropriate
host configuration can complete in a minute or so.  However, there are
many reasons why the delivery to the end recipient's mailbox may be
delayed for several hours.

To find out about the hotmail address, you need to look first in
Mailman's logs to make sure the post was sent, then in the MTA's logs
to find out whether hotmail accepted it.  This is usually not a
Mailman problem.
