I have the impression that the distrubution of the emails of the mailing lists is not working.

When the load on the machine goes over a certain number, sendmail takes a break. The changes that Brion made have the load running high -- over 20. This keeps the website going, but has the unfortunate side effect of preventing mail distribution.

I'm going to cut the MaxClients setting to 100 for a little while, to let the mailing lists function for a bit, and then bump it back up.
