[Mailman-Users] when does logs/post get updated?

[Ricardo Kleemann]

I have some more data on this...

I enabled the debug in SMTPDirect.py, and it shows that there really
aren't any problems. It shows that slowly a message is being sent out.

I followed the performance tuning suggestions that had the MAX_RCPTS in
Defaults.py at an optimal value from 2-5, so I set it to 3.

But does that mean that mailman is going to simply get stuck on one
single message distribution and won't process any others until this one
is finished?

I used to have these lists on another server and over there I had the
MAX_RCPTS set to a high number, but my mail server is set to reject
above 25 rcpts anyway so the end result that at max it would handle 25
rcpts. I remember that whenever a message arrived for the list (again
20,000 members) on the other server, the load average on the server
would go pretty high as it processed the list.

But now on this new server I never see the load avg go up. Is this
because of the MAX_RCPTS setting? What else would keep mailman from
efficiently handling the messages? 

The OutgoingRunner is just sitting there slowly distributing the message
and never seems to get to the next one.
