exim + dnsbl reject all the email

[Nox]

Hi think this is mi first post here, anyway i have spent the whole day finding a solution with no luck.
Here the problem, i have used for about a couple of months exim with dnsbl support on two DA box, and it worked great until yestarday, when exim started rejecting all the email, doens't matter if the email are spam or no, it reject the email sayng that is blacklisted.
I haven't edited or modified anithing, and that's why this problemi is driving mi crazy!
On my configuration i just use 2 bl spamhuas and spamcop.

  deny message = 500: Email blocked by SPAMHAUS - to unblock see http://tuxspam.in.nl/blocked.php?ip=$sender_host_address
       # only for domains that do want to be tested against RBLs
       domains = +use_rbl_domains
       dnslists = zen.spamhaus.org
# deny using spamcop
  deny message = 500: Email blocked by SPAMCOP - to  unblock see http://tuxspam.in.nl/blocked.php?ip=$sender_host_address

       hosts = !+relay_hosts
       domains = +use_rbl_domains
       !authenticated = *
       dnslists = bl.spamcop.net

But now i has been forced to comment the section related to the BL because exim is rejecting every email.
I can't see any error message through logs* so i'm totally lost.
I'm sure that the problem isn't exim but i can't figre what is going on.
Any help is much appreciated, thanks in advance.

You'll have to check your /var/log/exim/rejectlog for the period these domains were listed. I've just tested both good and bad IP#s at both zen.spamhaus.org and at bl.spamcop.net, and both worked properly, not returning postives for known good IP#s, but returning positives for known bad IP#s.
