The problem might be the message size. Mailman parses all the messages with 
python,who is a little unefficient.

For example, on my mailman machine, messages of size=300 KB required 300 MB of 
RAM for processing... and used up (+90%) the CPU (P-III-Xeon-550).

In my case, the solution was to reduce the message size,
