Sujet: Re: [Exim] Bypassing RBL check for authenticated users.
The change you suggested left my server open to relay.

Basiclly i want that authenticated user will not be checked agaist RBL
(SLOW)

here's my original ACL:

begin acl



#!!# ACL that is used after the RCPT command
check_recipient:
# Exim 3 had no checking on -bs messages, so for compatibility
# we accept if the source is local SMTP (i.e. not over TCP/IP).
# We do this by testing for an empty sending host field.
accept hosts = :

#!!# Spam control starts here:
deny message = rejected because $sender_host_address is \
blacklisted at $dnslist_domain\n\
$dnslist_text
dnslists = bl.spamcop.net : \
           blackholes.mail-abuse.org : \
           dialup.mail-abuse.org : \
           blackholes.easynet.nl : \

  # Accept bounces to lists even if callbacks or other checks would fail
