Over the last three days I have had a series of unexplained unsubscribes from one of the lists, and almost all of the unsubscribed email addresses are yahoo.com addresses. None of the admins has done a mass removal, so is there any way for me to determine why these email addresses were unsubscribed? Anything in the log files?

Check Mailman's bounce and subscribe logs.

This could be a result Yahoo rejecting mail from your server and
tighter bounce processing settings or more posts to the affected list.
