SPF has from day one been known to be broken with mailing lists. It's 
not "really bad", it's just what it is. There are other modes that SPF 
fails too like forwarding. Frankly I've tried to keep clear of "SPF is 
pointless", but it is actually pointless. It doesn't bring anything to 
the table that DKIM can't do better.
