Yes, that's mostly the DMARC problem.  We're painfully familiar with it.

One day I asked a guy at Google why they don't just whitelist incoming 
mailing list mail, since they clearly have a good idea where the list 
hosts are.  He said that legit lists send spam (actual ugly spam, not 
filter errors) all the time, either because a subscriber's account is 
compromised or the list itself is compromised.  Accurate filtering is 
remarkably complicated.
