Anything obvious in these messages? ( unknown recipients, joe-job bounces)???

Is this the same amount of messages you were processing before?

Have you tried turnin all the RBL's off in SA and just leaving a couple of known working ones on. (nb spamhaus will put you on their 'greylist' is you query them too much as part of their usage policy), So unless you've got a pay for feed I suggest you remove them from your setup given your message load.
