breakthru.com has a wildcard so ANYTHING you look for there will come
back with an answer, which exim's blacklist lookup is configured by
you to reject.

It's actually looking up 34.0.31.128.breakthru.com, which returns
208.88.180.117.  ANYTHING.breakthru.com returns that IP, so it will
always hit, which will always cause your mail server to reject.

You're using breakthru.com to do RBL lookups, but you shouldn't be.
Remove it from your dns blacklists configuration.
