I guess someone or some few people on the list are using e-mail addresses registered via DNS servers with some sort of pathologic condition which kills your server. You could probably put together a fairly simple script that loops through your list of addresses mimicking the DNS lookups that sendmail does and waiting for everything to go pear-shaped. That should help pin down the addresses that are causing the problem. Of course, it would mean killing your DNS in order to save it.
