[Mailman-Users] "Too many recipients" error & tuning

[nicolas at hushmail.com]

Hello:
        I posted to a list with 2000+ users, and got a

Too many recipients

error. It seems to be that the sendmail remote server choked when received an
email with too many recipients. The problem is that I can't find enough
documentation about the variables presented in ~mailman/Mailman/Defaults.py   
and ~mailman/Mailman/mm_cfg.py.

I think I should set SMTP_MAX_RCPTS to something as low as 20 (it is set to   
500 now), but DEFAULT_MAX_NUM_RECIPIENTS also seem a good choice. Which one   
affects the number of recipients of an outgoing message?

I've already checked the mailman-users archives and the mailman FAQ.

Besides the specific answer to this question, where can I find more
documentation about configuring mailman? I also want to know what MAX_SPAWNS  
do.
   
TIA
nicolas
