Yeah, but if you've done the performance-tuning stuff correctly (see 
the FAQ), then you should be able to handle a 40K list.  Mailman 
typically starts to see issues when you get into lists considerably 
larger than that.

And the performance enhancements that they're working on for 2.2 
should help things tremendously.

Trend Micro has announced that they will cancel the stop.mail-abuse.org
mail forwarding service as of 15 November 2006.  If you have an old
e-mail account for me at this domain, please make sure you correct that
with the current address.
