[Exim] dns_again_means_nonexist don't work for verify = reve…

Hi,

    I'm configurating verify the reverse dns, and set an acl to check this:

  require message      = You don't have reverse dns name [$acl_verify_message]
          verify       = reverse_host_lookup

I set dns_again_means_nonexist = * to reject all "SERVFAIL" or
"non-authoritative host not found'... but don't work... I have in the log:

2003-10-29 13:25:32 H=(mail.movilab.net) [195.53.251.5] F=<roig_p@???>
temporarily rejected RCPT <proigb@???>: host lookup deferred for
reverse lookup check

And

smtp02:/datos/logs/exim # nslookup 195.53.251.5
Server: dnsmad01.in.mad.eresmas.com
Address: 192.168.106.128

*** dnsmad01.in.mad.eresmas.com can't find 195.53.251.5: Server failed
smtp02:/datos/logs/exim #

comments ?!?!?

thankx, in advance
