  • RBL Rules Misfiring

    5 answers - 3344 bytes - related search similar search Add To My Delicious Add To My Stumble Upon Add To My Google Mark Add To My Facebook Add To My Digg Add To My Reddit

    Hello all.
    I searched my archive of the list, and couldn't find a similar issue. This
    is probably something I've misconfigured, but here goes. Running SA
    3.14via the Mail::SpamAssassin Perl plugin from amavisd-new. Have
    been running
    into a problem where some dynamic RBL lists are firing just because the IP
    is in the headers, not necessarily because it's the IP talking to my MTA.
    They are indeed IPs in the list but shouldn't be firing because they're
    really using their ISP's mail servers as you can see later in the headers.
    I'm *really* hoping this isn't intended operation and it's just something
    I've blundered somehow. Below is a piece of one of the message
    notifications I receive. I've been watching this on a couple small domains
    I own before putting it on our main one, and it's a good thing!
    Thanks in advance for the help.

    As a quick guess, you probably need to fix your Trust Path:

    No, I've got that set properly, as I didn't trust the autodiscovery. So
    I've already entered the class C for my MX's and SMTP's there for both

    K, after Googling around for a bit, I may have stumbled on something
    specifically this trust path thing. I had my trusted_networks and
    internal_networks set as my SMTP's and MX's class C network. Because of
    that, is that causing SA to look at the relay beyond the trusted network as
    the agent to compare the RBL to? Come to think of it, this didn't appear
    (or at least wasn't reported to me) before I set those values. At any rate,
    I've completely removed the internal_networks value, and changed the trusted
    values variable to 127.0.0.1. Eventually this will be behind a NAT machine,
    so I have to set *something*. If anyone thinks I'm on the right path, let
    me know. I'm also going to continue monitoring for this problem, so if it
    goes away now, I'll let the list know for posterity's sake. Thanks!

    The problem has indeed ceased since changing the setting. At first it
    didn't quite make sense to me as to why it was working the way it was, but I
    guess it makes perfect sense if you sit and think about it. A lesson for
    those who don't know, you never want your MX server to be a "trusted server"
    or you may have rules firing that shouldn't ;-)

    That's incorrect. You always want your MX to be trusted. SA will then
    check the IP that connects to your MX against most RBLs. Regardless,
    there are a few RBLs that SA will check all IPs against. Debug info
    makes it clear what exactly is being checked.
