Also, if people who mail to the list are posting from @yahoo.com or
@aol.com addresses, you need to deal with DMARC.  In brief, upgrade
Mailman to 2.1.18-1 and use dmarc_moderation_action to wrap the
message or munge the From header to Yahoo/AOL's liking.  (Note that
this is a problem with *any* mail posted to a list by a Yahoo/AOL
*sender* for a large group of subscribers, who need not be Yahoo or
AOL users.  Gmail for example always puts mail from Yahoo via list
that hasn't been munged into Spam, even if it doesn't qualify as spam
on any other metric.)
