The server you are thinking of might be a bit weak for the size
of the mailing list(s) you are considering.  On the other hand,
if you are running an announcement only (no replies or other
interaction by your zubscribers), you might be looking at up to
40 msgs/sec output with a really fast MTA and 7Mbps connection.
One outgoing distribution, on a 35k message requires 1.4Mbps of
bandwidth to support 40 msg/sec.

One of these lists distributing a 35k message would eat a full
T1 pipe for over 7 hours.  If you have varied bandwidth between
sending and receiving data, it is your send pipe that can fill
up.  This calculation assumes a separate message for each and
every recipient totalling 35Gb of data to move across the pipe.

How long does it take you to copy 35Gb of data from one computer
to another on your local (100Mbps?) network?  Now factor in the
speed of your internet connection.
