yes, the question still unanswered by this list, is where the switch is to turn OFF attachments.

I think you need to look into the "content filtering" section of the web interface. There are two options: filter_mime_types and pass_mime_types. They'll allow you to explicitly control what mime types to allow through in Mailman 2.1.x.

Also, I suspect that you haven't looked into the FAQ system on this one:

http://www.python.org/cgi-bin/faqw-mm.py?query=attachment&querytype=simple&casefold=yes&req=search

I find eight results on "attachment".

if you will read the three or more requests to this list, you will see that I have stated that I have seen and read and done all of the above and that I am still looking for a single switch to turn off all attachments. If Yahoo, using this same software although blended with EZMLM and a mess of scripts, can do this one thing, then it should be able to be done by the programmers of this software. There are a couple of other requests I have made at the same time that have still not been acknowledged or answered.

Hi Chas..

What I've done on my lists is, under Content Filtering, where it says "Remove message attachments that don't have a matching content type. Leave this field blank to skip this filter test.":

multipart/mixed multipart/alternative text/plain

That seems to strip most all attachments that have tried to be posted to my lists... :)

Hope it helps, Glenn

It is poorly written and confusing but if you turn it around, it says "keep attachments that do have a matching type."

actually, you (I) do not want ANY attachment. PERIOD!!

Gee, maybe you should start writing code, eh?

If you want a single big red switch to "Do What I Want", then you had better define very precisely just what exactly it is that you want. So far as I can tell, you haven't done that yet, and people have been trying to point you at the resources and methods that are available to do things that appear to be related to your question.

content filters will take care of mime stuff inside the message body. such as the richtext code of a vcf or of a html tagged, quoted and inclosed in the message.

what i want to delete is stuff which is ATTACHED to the body of the message, a scond part of the message. it could be multipart or a part of the body. it is more likely a movie, a picture, a sound bite, etc. all of those should be stripped. it certainly happens in Y!G and we should be able to do it here.

again, the final test is - nothing which is not Plain Text, US-ASCII gets into the elist. That is the final test. Anything which does not meet that "filter" should be stripped, deleted or better - rejected to the sender with a fault message.

thanks chas

For example, if a message is PGP signed, the "Content-Type:" header might be "multipart/signed", "multipart/mixed", or there might be no MIME headers or formatting at all, and the message is in plain ASCII with internal formatting that PGP understands. If the message is in HTML, the value for this header might be "multipart/alternative".

Oh, and I forgot uuencode -- using this tool, the message will 

likely appear to be in plain ASCII, but most MUAs will display the encoded part as an attachment. Do you want to ban them, too? If so, that's a lot more work.

My point is that this is not a simple process.  You need to be 

specific about what you want to eliminate, or what you want to allow. If you can provide that level of detail, then there should be existing tools that you can use to implement your choices, and we can help you find them.

But there isn't any "Big Red Switch", nor is there ever likely to be one.

As far as I can see, Mailman will do that for you. But first...

You do not seem to understand how mail is constructed. "Strip all attachments" is actually vague because e-mail was not originally designed with "attachments". Terms such as "attachment" and "message body" are not well defined because a layperson would use a term like "attachment" in a way that does not map unambiguously (or even at all!) to technical details. Then again, the usage might correspond *exactly* to technical usage. Without details, this situation is ambiguous. You may wish to say that in this debate, "attachment" refers to Mailman's user-interface usage of "attachment". In that case, I don't see why you are not already satisfied with Mailman's options (read on).

Asking to "strip all attachments" could involve a number of activities and the correct answer will depend on your circumstances. For example, here are some distinct acitivites which could all be described as "stripping all attachments" in the context of MIME (RFC 2045 and so on): retain only the preamble and the epilogue; strip all MIME entities with 'attachment' disposition; convert messages with Content-Type: text/html to plain text; aggregate all text/plain segments and drop others; retain only the first text/plain segment; and more.

Furthermore, what is "plain text"? HTML is plain text. text/enriched is plain text. From your recent posts, we can rest assured that you want only the text/plain content type (even though others might allow text/enriched and text/html). Mailman gives everyone the ability to make a range of choices. Yahoo, on the other hand, might make its own choice and give it a particular name.

To help solve your problem, I have just created a new list on a host running Mailman 2.1.1. I have subscribed myself and verified that I can send a GIF-format "attachment" through the list. I am now visiting the "Content Filtering" configuration category. I see an option to turn on content filter. I think it needs to be on.

Next, I see an option to remove message attachments that have a matching content type. That doesn't sound like it fits your requirements, so I'll move down the list.

The next option is to remove attachments that don't have a matching type. The default option allows multipart/mixed, multipart/alternative and text/plain. That sounds like exactly what you want, so I leave it unedited.

The next question relates to converting text/html to text/plain. I don't think you need it, but I'll leave it on its default setting anyway (it is turned on).

The next option is the "action". I'll choose "reject", so that I get some feedback when I test this configuration.

I now re-send my GIF test message. My message was not rejected but was instead sent through the list with the GIF removed and my text/plain entities intact. This sounds like what you want.

So basically, Mailman 2.1.1 comes with your desired settings entered by default (other than "turn on content filtering"). If this is not the case, perhaps you can try again to explain your requirements.

that is why I do not like this system of content or pass filtering. I simply want to state, PLAIN TEXT only, NO attachments period.

You have clearly misunderstood the documentation and rejected the correct advice that was given to you. If you feel that the English documentation for Mailman is not well written, or you would like the interface written is a different language, you could contribute the necessary changes yourself.
