You mean commercial systems that would be suitable for use in an 
Enterprise environment?  Not that I am aware of.

There are some tools like SpamAssassin that can be configured to have 
a database that stores the settings of an individual user and then 
applies those to the incoming messages, but that's non-trivial to set 
up and manage.  It can be done, but it takes some work, and there's 
definitely a cost that you end up paying in terms of higher 
administrative overhead in managing that system.

And procmail can be configured to run rules for processing the mail 
for each user as it is being delivered to their mailbox, and take 
various different actions with the message (file it to a separate 
folder, throw it away, run other programs, reject it, etc...).


Typical anti-spam appliances that I've seen would be like things from 
Barracuda or IronPort, and I don't know of any such appliances like 
this that have these kinds of features.

Personally, I would recommend avoiding the Barracuda appliances, 
since they come programmed by default to do some pretty stupid 
things, and they don't scale that well.  I've heard better things 
about the IronPorts, however.

Ahh, now there you could definitely be caught by people on the other 
end who are running into those SpamAssassin or procmail-type per-user 
filters.

[Mailman-Users] corporate spam filter operation

[Matt Morgan]

This question is a little off-topic.

Are there corporate, enterprise spam-killing services that work on a
user-by-user basis, rather than a message-by-message basis? For example,
where the same message, sent to a few different people, might be rejected as
spam for one recipient but not others?

I'm seeing failures in patterns I didn't expect. We often have many members
in the same domain. I thought I'd see that every message to a domain was
rejected (because it was judged to be spam), or that most of them would
succeed (because it's not judged to be spam, but maybe we have a few old/bad
addresses).

What I'm seeing is that often, about 50% of the messages to a domain are
rejected. It seems like too many for them all to just be bad, old addresses
(although that's possible--this list has not been updated for a while), but
too few for them to have been rejected by spam filters.

I'm delivering messages individually, in case that matters.

Any thoughts/opinions?

Thanks a lot,
Matt

I'm not aware of any convenient way to merge two .mbox files in time
sequence, but it wouldn't be to hard to do, in Python at least.

But I'm confused about what you did and what didn't work. I think if
you have two .mbox files and you do something like

bin/arch --wipe listname /path/to/first.mbox
bin/arch listname path/to/second.mbox

Or I gather you concatenated the two .mbox files into
archives/private/listname.mbox/listname.mbox and then just ran

bin/arch --wipe listname

In either case. you should wind up with a pipermail HTML archive with
the messages more or less in time sequence. Is that what you did? Is
that not what happened?

Or did you expect bin/arch to resequence the input .mbox file. It won't
do that; it just uses it as input; it doesn't rewrite it.

[Mailman-Users] merging 2 mbox files

[Mark Heer]

Hello,

We are moving from majordomo to mailan.  We use 2 mail hubs to handle mail 
service so mail can be handled by either machine which means some archive 
entries for a particular list will end up on mx1 and other posts may end up in 
the archives on mx2.  I need to combine the archives into 1 for display on our 
web archive - which is on yet another machine
running mailman but not the mx functions.  I attempted /bin/arch --wipe 
listname but it did not re-order the list by time sent/proper sequence., it 
just reproduced the file just as I had concatenated it. Is there a way to merge 
2 same list mboxes into 1 properly sequenced mbox?  

Thanks,

Mark

Nothing in this area has changed since the message you link to was
posted.

It is currently not possible to filter based on the content of a
message part without a custom handler or other form of patch.

You could add this request to the comments at

[Mailman-Users] Content Filtering for Body Text

[Cyndi Norwitz]

My mailing lists have a policy of disallowing copyrighted material without
permission.  I have a couple people on moderation who do not understand
this and post such things frequently.  But I want to keep most folks off
moderation if possible as it improves the flow of the list and reduces my
workload.

Once in a while, someone (who isn't moderated) forgets and posts an entire
published article.  Almost always, it's accompanied by one of those "fair
use" statements that someone made up a while ago and is used on everything
(I've seen it on press releases, government documents being forwarded, and
posts that correctly give a link and a single paragraph for context).

What I'd like to do is set up a filter that scans the content of the body
text for a phrase like: "FAIR USE NOTICE" or "Title 17 U.S.C. Section 107."
I would like those caught posts to go into the moderation queque ("hold"
not "reject" or "discard").

The content filtering in the web interface is for attachments and I'm
afraid to fiddle with it since I've had really bad results from trying to
use it before on a test list.  The only other thing in the interface I see
is the ability to filter based on text in the header (Privacy: Spam).

So I searched the MM FAQ and the archives of this list and came up with the
basic answer that, no, this is not possible unless you filter posts with
procmail prior to being processed by MM (something that is impossible for
me to do since my MM is run by my ISP) or use a patch (which is complex and
requires root access).

An example is:
http://www.mail-archive.com/mailman-users@python.org/msg30851.html

But I can't find anything newer than 3 years.  Perhaps something has
changed since then?  Is what I'm asking possible without a major
workaround?  Might it be possible in the future, perhaps as an extension of
the spam filters?

Thanks,
Cyndi

To be more specific, I suspect the original message had a structure
similar to the following (except the jpeg image had content-type
application/octet-stream)

multipart/related
multipart/alternative
text/plain
text/html
image/jpeg

I tested this with the current scrubber and with the 2.1.4 scrubber.
The 2.1.4 scrubber produces the result you see in your archive and the
current scrubber produces the expected result with the text/plain body
in the message and the text/html and image/jpeg parts scrubbed.

Did you edit the listinfo page template for the non-working list?

If so, you probably lost or misplaced the  tag.

[Mailman-Users] Problem with new subscribers

[Carlos Corredor]

Hello again:
 
I have two lists. In one of them, I can add new members by mass subscription
only - adding a member using the general list information page does not
work: nothing happens - no response email of any kind, and of course, the
user does not get subscribed. In the other list, everything works as it's
supposed to.
 
I have ascertained that ALL the settings in mailing list administration are
exactly the same in both lists, The lists are on separate domains.
 
What could I possible have done to cause this problem?
 
Please note that I am on a shared host that has a control panel (not
cPanel), so I have to work from the administration page, I do not have
access to the Python source code.
 
Any ideas?
 
Carlos

The short answer is Mailman 2.1.4

>From the above archive entry

Skipped content of type multipart/alternative-- next part
--
A non-text attachment was scrubbed...


So the 'body' was multipart/alternative. There have been many changes
to the scrubber since 2.1.4, and I think that currently, assuming the
multipart/alternative part had text/plain and text/html subparts, the
text/plain part would be the body in the archive, and the text/html
part would have been stored, but the 2.1.4 scrubber didn't do that
well with 'not so simple' message structures.

The monodrama, with songs.

Written and Performed by Tayo Aluko
Accompanied by Michael Conliffe (Piano)
Directed by Olusola Oyeleye

Monday, April 7, 2008
8PM
Humanities Hall Little Theatre
UC Irvine

THIS EVENT IS FREE AND OPEN TO THE PUBLIC

Paul Robeson is a great and famous actor, singer and civil rights  
campaigner.

When over the years he gets progressively too radical and outspoken  
for the establishment's liking, he is branded a traitor to his  
country, harassed, and denied opportunities to perform or travel.

Just as physical, emotional and mental stress threatens to push him  
over the fine line between genius and madness, he is summoned to  
appear before the House Un-American Activities Committee, to give the  
most difficult and important performance of his career.

The play features some of his famous songs and speeches, and  
highlights how his radical activism caused him to be disowned and  
disremembered, even by the leaders and descendants of the civil  
rights movement.

This production is co-sponsored by Student Affairs, the International  
Center for Writing and Translation, Department of Music, and
