When load increases past 20 on a box, it starts queueing mail instead of processing it for delivery. This works fine, generally. However, if load doesn't subside quickly after doing this, the queues get large and take a long time to empty. The issue of "more mail" (read: more junk) getting shoved down our system's throat every day is compounded by the fact that the spam assassin rules continue to get more complicated to cope with "more junk." This leads to higher overall loads and more time spent processing each message. You can look at the stats and see what is happening: http://project.mail.msu.edu/~rrdtool/ It's important to note that while looking at the stats, you consider that some queued mail is trying to be delivered to a non-local host which is not available. We have planned some design changes to our delivery process which should fix this problem, but is dependant on the addition of some hardware (we've requested funding, and will find out about that at the start of the fiscal year). In the meantime, we are working on a stopgap. When we make a change, I will ask the group to note any continuing issues.
