Arnd,

I don't know if it would work or not, but id be looking at running it in

And some more similiar messages.

Can anyone clue me in on how to get those two forsaken libs cleanly

Binaries are, indeed, released through vendors. 
See http://www.postfix.org/packages.html for a listing of various links
to packages of postfix. The postfix.org website doesn't have the
packages, but links to them all. 

According to the mirrors, Things are done according to the IBM public license,
http://getmyip.com/mirror/pub/LICENSE

Read the IBM public license and take it from there. 

Hope this might help clear up any licensing/packaging issues with
postfix.

Sorry, I cannot comment as to the status of qmail, since I have chosen
to use postfix instead.

> share?

search the archives of this list.  MTA comparisons have been discussed many
times.  i've made the arguments several times before and i'm getting bored of
it.

to summarise:

1. because qmail is so different from other MTAs, it is a dead-end trap, just
like proprietary software.  bernstein doesn't believe in making any effort to
assist people who were using other MTAs and want to switch - migrating to qmail
is a pain, and migrating away from it is just as bad.

2. it has severe licensing problems, which mean that the code basically
stagnated years ago.  no patches are ever accepted into qmail, and the author
doesn't appear to be interested in making any improvements (in his estimation,
it is already "perfect"...ignoring several glaringly obvious faults and lacks).

the license means that using qmail is a reversion to the bad old days before
free software became ubiqitous - the late 1980s for instance.  back then you
had to hunt for the original source (easy enough), then hunt for every patch
that you needed to make it useful, then apply them (and hope that the patches
are compatiblediscovering by trial and error that they can be compatible
but only if applied in a particular *undocumented* order), then compile and
install it.

3. bernstein insists that you discard years of practice, tools, and techniques
and start from scratch.  if you don't like it, then you are a moron because
bernstein is Always Right so don't complain.

4. the configuration is truly bizarre.bernstein has his own non-standard
directory structures, and a liking for many little files.  many of these files
are 'magical' - the contents are irrelevant, mere existence of them alters
behaviour of the program, and even causes programs to be run automagically.

this makes it impossible to experiment by temporarily commenting out particular
lines - you have to delete a file, and then hope you can remember what it was
called if you need to re-enable that feature.

it also means that there is no config file containing comments to serve as
working reference documentation.

5. bernstein likes to reinvent the wheel.  he does this (and does it badly)
without regard to whether the wheel actually needs to be reinvented or not
(e.g. ucspi-tcp).

this is compounded by the fact that it is a complete PITA to use any of his
programs without using all of his programs.

6. the author is a rude jerk.  this is undisputed, even by those who actually
like bernstein's software.


craig

ps: as for postfix being better - it is:

1. free software, with a real free software license (IBM public license)
2. actively developed, with a friendly principal developer and helpful
developer & user community.
3. backwards compatible with sendmail, so migration is easy
4. secure
5. fast (much faster than qmail)
6. the best anti-spam features of any MTA available
7. more features than you can poke a stick at

Bjornar,

I have run them all at one time or another. We currently are running
qmail for our main MTA's but have postfix running on the sidelines.

I don't care to debate MTA's any more. Akin to debating which is a
better automobile. So I say, "pick a horse and ride".

Now that said, it really depends on your experience, time focus, OS and
hardware. qmail does the job, round the clock. So does postfix.

You mentioned nothing specifically about what you wanted to do with your
MTA relays ? Hard to help. qmail & postix will both relay.

Matter of taste - I find postfix' log files are orders of magnitude easier to 
read than qmail's.

Also matter of taste - I could not wrap my head around qmail's configuration 
ideology. postfix imho stays closer to what I expect from a program in the 
Unix world.

These two made the decision for me quite early, and I'm happy with postfix 
now, so I haven't gone back to see how well qmail would have dealt with 
requirements.

A third argument - also not of the hard facts kind - is that I don't like 
qmail's licensing.

There is a list of FTP sites that hold the

I have apt-get install'd postfix so I suspect this is not true. If this is

The biggest complaint I've heard about qmail is that its license requires
you to install binaries according to the taste of the creator. This means
that things are the same on Debian solaris and redhat but also makes it
less "standard" if all you use is one distribution.

Having an interface to SA on steroids was appealing. With the virusprotection clamd 
has nothing to do either now and the MTA just purrswith a lot less load. The cat's

This will only help if you're users have login capabilities, but I use a
cron that calls, I don't know if this is doable w/out login shells for
the users.

for i in `ls /home/`;do  user=$(echo ${i} | awk -F/ '{print $1}'); su -
${user} -- sa-learn --spam /home/${user}/mail/spam; done;

Obviously this is for spamassassin, but there must be a learning
capability with bogofilter. It ensures that the user just has to throw
their spam in ~/mail/spam and it updates their bayes db's. Then a
standard .procmailrc in /etc/skel and all the users home dirs to check
for headers.

I find this is better then a global bayesian filter because with all of
the users, the Bayesian filter tends to useless. I do use SA w/out
bayesian filters at the top level though.

We liked SA but was very tired of the perl usage on the MTA. Se we
searched and found the Barracuda. Now we have Bayesian and more and a 
very nice solution, not on the MTA. I have not looked back.

We ended up cheating by symlinking and removing the old debris :) But If I
run into additional issues I will attempt your approach. I appreciate the
help.

Run spamassassin and bogofilter in parallel for the first months, and use sa 
to train bogofilter?

I think separate databases per user are highly beneficial - some people hardly 
have any HTMl mail, for instance, others do - same with mail in foreign 
languages.

Bayes filter at ISPs

2004-02-19 Thread Adam ENDRODI

I'm considering replacing the current SpamAssasin to a true
Bayasian filter (bogofilter, actually) on a mail server, because
in personal daily usage, it has proven to be a better (faster
and more accurate) solution for me.

I suppose many of you use Bayesian spamfilters at the ISP level.
I'd like to ask how do you teach it to separate ham and spam
correctly?  In particular, how do I select a representative set
of ham and spam?  Is it a good idea to deploy bogofilter for an
entire organization at all?

thanks,
adam

I know, smokeping is a graphing layer above other programs (including
echoping).
