Αντικείμενο: RE: [Exim] Rbl checking only for incoming messages
Well,
I tried the recommendations from here and it did not work again.
Here is my whole ACL. It seems that now no more rbl checking is done.
The reason why I want to turn rbl checking off for authenticated local users
is that DSL subscribers in Europe seem to be included in the dnsbl.njabl.org
list and that would mean they are prevented from sending out mail even
though they have a valid account on the machine.
Here is the 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 = :



  # Accept bounces to lists even if callbacks or other checks would fail
  warn     message      = X-WhitelistedRCPT-nohdrfromcallback: Yes
           condition    = \
           ${if and {{match{$local_part}{(.*)-bounces\+.*}} \
                     {exists
{/usr/local/cpanel/3rdparty/mailman/lists/${lc:$1}_${lc:$domain}/config.pck}
}} \
                {yes}{no}}


  accept   condition    = \
           ${if and {{match{$local_part}{(.*)-bounces\+.*}} \
                     {exists
{/usr/local/cpanel/3rdparty/mailman/lists/${lc:$1}_${lc:$domain}/config.pck}
}} \
                {yes}{no}}


  warn     message      = X-WhitelistedRCPT-nohdrfromcallback: Yes
           condition    = \
           ${if and {{match{$local_part}{mailman-bounces\+.*}} \
                     {exists
{/usr/local/cpanel/3rdparty/mailman/lists/mailman/config.pck}}} \
                {yes}{no}}

                     {exists

                {yes}{no}}
