Spamassasin is extremely slow. (it does pattern matching among other
things).  Bayesian filtering has been shown to be many times faster.

Drop Spamassasin and replace it with Bogofilter.  Then drop your RBL
filtering and you won't have to worry about the false positives 

Further you won't have scrutinize a huge stream of possible SPAM to make
sure that there are no false positives in it.  Something you've just
indicated your going to start doing everyday.  Whee - What fun!  Oh -
wait - you've just given yourself the job of being a spam filter!

Ah- some do-ish, some don't-ish.  No system is perfect and when an RBL
isn't perfect (and none of them are), innocent people get their mail
rejected.  This causes serious hardship in some cases!

Its a Bad Thing(TM).

Its also the most frequently heard complaint about RBL's (This is my
impression only, not a published fact that I'm aware of, after all 
who's counting? :-)  )

Did they notify the owners of the site that they were being put on 
a blacklist?

If you're going to run a "McCarthy style blacklisting operation" you
should at least have the guts to tell each victim that you are putting
them on the list.  Clearly no one at GNHLUG was aware that they were
somehow being blacklisted.

If your going to claim that the RBL owners would get too much grief from
people if they actually notified folks they were being blacklisted then I would
have to say that running an RBL should require a substantial amount of
fortitude.  A group or person without the courage to stand up and defend 
the principles that they are operating a blacklist under is not the kind
of person(s) that should be in charge of such an effort.  It degenerates
into a revenge list or falls prey to other vices.

OK, the new Spamassasin does better than the old one.  Try a well

all the other stuff SA does will become necessary, just slowing things

We're in 100% agreement. That's why I use my RBLs, *plus* other traps and

The amount of spam that actually makes it through is *very* low. But the 
amount that has to be processed by spamassassin is very low to begin with.

Also, the time that it takes for an address to get into lots of the RBL is 
generally pretty low.

In the absence of consensus on this issue, it should be possible to 
add a whitelist to your system so that domains you explicitly want 
to accept (like gnhlug.org) can skip over the RBL-check entirely.

Right - which means the RBL technique is failure-prone whenever people are part 
of it. No one pays attention to something they see all the time. So its always

So I'm saying that its not that important to correct RBL's which have

Clearly the RBL's which list all of uunet and all dynamic IPs have more
bad information than they have good information about Spam sources.

There are many RBL's and more are popping up as we go forward.  While
some are worse than others, ALL of them have erroneous information in
them that will cause you to throw away real email and at the same time
they don't prevent spam from getting to your system.  Eventually this
will cause RBL's to become un-trusted and eventually less used.  Since
some people have falsely submitted domains/ip's to RBL's to
harm the owners/users of same, and more people continue to do it all
the time, its clear we will never be able to trust the RBL's

I'll admit its nice and easy to say "Oh Ip 192.x.x.x? Sorry, you're spam,
disconnect" before the email can arrive on your site/system.  But this
is one time where taking the easy way out is the wrong way to do it.

For Non-ISP's, using RBL's will ultimately do more harm than good.
(False positives causing missed email)
(ISP's aren't harmed when they block their customer's real email as spam
so they can use an RBL without fear.  Most of them will not lose enough
customers for it to ever be a problem, unfortunately.)

In order to intelligently stop spam you cannot filter on RBL based IP
addresses/domains.  You must filter only on content.  The trials which
the Bogofilter people have run on real email indicate that it more
accurate than any other way of doing it.

The problem is that easynet.nl (and a number of others) DO NOT remove

And a number of others do not validate the requests to list spamming
addresses.

So, if your system is coopted by a spam worm, then your system is dead as

Lots of interesting commentary here.

* Why do I use RBL's in the 1st place? Because I would much rather reject 
mail before it's received than after. If I filter it out after then they 
know that I have accepted it. The fact that they always try multiple times 
after a 500 series error code is just even more grating. If you don't run 
your own domain, then you really don't have access to this technique. 

* Derek Martin said that you have no way of knowing if you've missed

senders were rejected. (I just wasn't paying attention.)

* Jeff Kinz says it's not important to make sure that you are accepted by

an RBL but you should at least know why they are rejecting you and to 
have at least made the effort to try to clear up the conflict. Like I 
mentioned earlier, some RBLs base themselves on vastly different criteria. 
Some criteria are acceptable and some are not (to me). For example, I 
mentioned one RBL that rejects all clients of uunet. Another rejects all 
dynamic ip addresses. You have to decide what sets are right for you.

This problem between easynet and codemeta issuch an incredibly small 
factor of how much I reject on a daily basis, that I would recommend 
anyone who wanted to use a good rbl to *start* with this one.

No, its not important to do that because there will always be another
RBL list somewhere which is also broken, especially since RBL's are
proliferating at an increasing rate.


All it does is demonstrate that the concept of RBL's (as currently
implemented), are broken and not reliable.

Bayesian filtering programs such as Bogofilter (see sourceforge) 
not only do a better job, in my experience they produce fewer false
positives.   No RBL is needed.


I concede that some form of publically or widely participated in "trust
metric" measuement might do a good job of creating a dependable RBL but
that would require a great deal more effort and watchdog mechanism than 
is currently being expenede.  I doubt it would ever happen and they
would still not stop spammer who move rapidly from ISP to ISP.
Bogofilter and similar tools can and does stop them, but based soley on
the content of the email and customized to your personal idea of what
spam is.

  Why should that be our responsibility?

  Strictly my opinion here: I take a very "lazier fair" attitude toward
blacklist services.  There are those who hate them and think they should be
sued/illegal/regulated/etc.  Then there are those who think we should all
bow down before them.

  I consider them a vendor, like any other.  They provide a service.  You
can choose to use their service, or not.  You cannot hold others responsible
for the service they provide.  If your vendor is feeding you incorrect
information, it is not our responsibility to correct your vendor.  If you
feel your vendor has incorrectly listed GNHLUG, it is your responsibility to
correct your vendor.

Personally, I think that's a bad way to look at it.  Spam is our problem 
and if we were vulnerable to either unauthenticated proxying or SMTP 
relaying, then it's -OUR- problem.  They provide easy to use tools to look 
it up.  They have an awful lot of IP's listed, so I question their 
legitimacy, but if Steve Orr has faith in them, it's worth looking 
at.

That's like saying a car with an emissions problem is the driver's problem 
and the state shouldn't care about it.

  It actually appeared that rogue.codemeta.com (GNHLUG's current mail
server) is the system that is blacklisted.

  You or anyone else is welcome to find out why rogue is blacklisted with
these people.  If there's something reasonable we can do to get off the
list, we can probably arrange to have it done.  :)

  Myself, I don't have much patience for people who use a single third-party
blacklist as a sufficient criteria to block mail.  They are too unreliable.  
Better to use them as one factor is a weighted-scoring system.

  Ultimately, if your system is blocking mail, it's your problem, regardless
of why you made that decision.  If you are basing your decision on a
third-party information source that is not doing what you want, take it up
with that third-party.  :)

Have you attempted to download the list from easynet - the one that listed 
it?  It's rediculously long I seriously wonder if they have an ip in 
every c block in existence.  It's so long that less than halfway through 
downloading it with my browser, I had to bail for fear of running out of 
memory.

Apparently, it thinks rogue.codemeta.com is an open proxy.

If you use their lookup tool, you get:

First off, I neglected to apologize for the snafu in my last message. Yes 
it really was my spam filtering that was causing the problem.

But I really do think that it's somewhat important to find out why easynet
thinks that gnhlug.org is a spammer? I doubt that it's the case, but have
we checked that we are not a relay (or never were). Whatever the reason
is, we really should track it down and prove to them that we are worthy of
not being blocked. If the reason turns out to be bad *then* we can condemn
easynet.

Footnote: I do use a fairly carefully selected set of RBLs. (If anyone
wants them just let me know.) And yes on rare occasions I can run into a
small snafu with them. (One time I used a new rbl and it shut off all
clients of uunet.) But in my RBL experience blackholes.easynet.nl is *the*
most productive RBL out there. I reject the majority of real spam every
day just from this.

  Are you sure it is not your spam filtering that is/was blocking said mail?  
Have you tried unsubscribing/resubscribing now that you've made exceptions
for GNHLUG/CodeMeta in your spam filtering?

I get a few of these starting Jul 1 (my logs *do* go back further).

So it looks like we have two problems. One is that I am really not

Two is that somehow gnhlug.org got put onto the spammers list. easynet 
really is my best RBL and I'm not willing to not use them. I did add an ok
