[Mailman-Users] performance tuning for sendmail and local users

[Iain Pople]

Hi,

I am setting up a Mailman instance that will deliver to around 10,000 
local users. Can anyone suggest appropriate settings for Mailman and 
Sendmail to optimize performance?

Specifically I am interested in suggestions for the following Mailman 
options:

SMTP_MAX_RCPTS
SMTP_MAX_SESSIONS_PER_CONNECTION
MAX_DELIVERY_THREADS

thanks, Iain.
