Things like SPF and DomainKeys/DKIM tend to affect all mail from the
server. It is unlikely that they would be related to an issue of a
member receiving mail from one list and not another on the same
server. Such an issue might possibly be related to a recipient's
having list_a-bounces at example.com but not list_b-bounces at example.com
in her address book.

What is in your server's MTA logs? Are the messages to LIST B
recipients being sent and accepted by the respective recipient MX
