Easy to do.
Write a small piece of C code that forks N processes with 100 < N < 1000
and let each of those process send one mail to the server. The body of
the mail can be anything but I suggest you use something like ``head X
/dev/urand'' where X is a poison time serie. Make the mean of X
centered around 20k of data and let it have a maximum value of (say)
50megs with a small variance so that most (80%) of the mails are small.
Do not use a Pathetic Excuse for a Real programming Language or any
other scripting language or you will kill the sending box.
The find a couple of PCs to hammer your server with it. It should take
you less than a day to code and test. Then you have a mailbommer of
kings.
