Weird RBL Reject

khoonchee · Feb 20, 2008

Hi Guys,

We have RBL implemented on the server side which are not using the default WHM built in RBL but a custom RBL in the exim.conf.

user1@domain.com is not able to send email out due to the local IP is being listed in the Spamhaus. Surprisingly, user2@domain.com, user3@domain.com..etc which is on the same office network and using the same public IP is able to send out the emails and exim is not logging that the sender's IP is found to be blacklisted in the Spamhaus database. Only user1@domain.com connection is being dropped

Here's some mail log which I grabbed out:

2008-02-20 16:57:01 H=111.111.111.111.rdns.net (computer1) [111.111.111.111]:2356 I=[222.222.222.222]:25 F=<user1@domain.com> rejected RCPT <user1@hotmail.com>: rejected because 111.111.111.111 is blacklisted at sbl-xbl.spamhaus.org

2008-02-20 17:15:36 1JRl3A-000538-BJ <= user2@domain.com H=111.111.111.111.rdns.net (computer2) [111.111.111.111]:4449 I=[222.222.222.222]:25 P=esmtpa A=fixed_login:user2@domain.com S=2658 id=003a01c873a1$65011dc0$2f035940$@com T="Test mail" from <user2@domain.com> for abc@gmail.com

We are using the following RBL config in the exim.conf

# RBL List Begin
# Always accept mail to postmaster & abuse in any local domain
accept domains = +local_domains
local_parts = postmaster:abuse
# Check sending hosts against DNS black lists.
# Accept all locally generated messages
# Reject message if address listed in blacklist.
deny message = rejected because $sender_host_address is blacklisted at $dnslist_domain\n $dnslist_text
!hosts = +relay_hosts
!authenticated = *
dnslists = sbl-xbl.spamhaus.org : bl.spamcop.net : list.dsbl.org
# RBL Bypass Local Domain List
!domains = +rbl_bypass
# RBL Whitelist incoming hosts
!hosts = +rbl_whitelist
#RBL List End

Anyone have any ideas of this?

Could it be that the domains that the ones that can send through exim are listed in your whitelist files and so the RBL's in those instances are not checked?
