You go find  the user with a big  LART and explain to him that  next time he
puts  the attachment  on a  web page  or a  file server  and references  the
location in his Email :-)

You should  also restrict your message  size acceptable on the  list back to
100KB (that's a mailman option)

(mostly) ok. I think the bottleneck was probably among those:
- memory (your machine probably started swapping)
- disk I/O
