Hi,

I have a question about the way sendmail works.  I have been toying with
the idea of setting up some kind of an archiver server and I want to take
best advantage of the system.  In our case our only connection to the 
net is via uunet which we call once at night.  The issue discribe below
is only important if I am sending "large" mail files.

Lets suppose I send the same message to 20 users on the net.  For this
example lets say 10 of the users are on cpu1.com and 5 of the users are
on cpu2.com and 5 of the users are on cpu3.com.  My question is how many
times is my message sent to uunet:

1. 20 times (once for each user) because sendmail is a pretty dense
2. 3 times (once for each CPU) because sendmail is kind of smart
3. Once (and copies made as needed on uunet) because sendmail is very smart
