Why do you refer to these archives as being of Maildir mailing lists? What is the actual software that created them.

The original sentence I got from the provider said, translated to English: the format is vpopmail (qmail - courier). I must recognise that I'm not able to reconstruct the pathway that has led me to say that we were using Maildir. Ezmlm was the actual software that created that lists. Both, regular maildir account subfolders and ezmlm subfolders are stored in the same folder in the archives structure. I think this was the reason why I interpreted all of them are Maildir subfolders.

Those archives don't contain new, cur and tmp folders all

Within /archive, there are two folders, 0 and 1, with a number of files, each of them containing one message, and an index file.

This looks vaguely like Maildir, except Maildir has no index file. What is in the index file(s)? What is the difference between 0 and 1? Do they each contain some complete (including all headers) messages, i.e. each contains a set of messages that combined are all the messages, or does one of them contain message headers and the other bodies, or does one contain messages and the other contain metadata about the messages?

Here you can access to the whole structure of one of the subfolders...

http://datasource.idisantiago.es/r.users/

Here the indexes of subfolders 0 and 1 (ISO Latin 1 encoding required for a correct rendering of all the characters)...

http://datasource.idisantiago.es/r.users/archive/0/index http://datasource.idisantiago.es/r.users/archive/1/index

It looks like each subfolder in the row within /archive holds a maximum of 100 messages numbered from 0 to 99.

Each file within subfolders 0 and 1 contains a complete message, including attachments (this is a guess, as files' size ranges from few Kbs to several Mbs).

...

Please, does this made sense for you? Am I completely lost? How could I deal with this "archives" to move them to mbox files and get them imported our brand new Mailman server?

You just need to add a *nix From_ separator to the beginning of each complete message and concatenate them.

If you can show me what's actually in some of those files, I could

The link above gives access to a whole subfolder!

possibly create a conversion script for you.

It could be as simple as something like

cat archives/0/* archives/1/* > mbox

except for the index files, but probably not.

That's Ezmlm. Have you tried something like this:

Get your Ezmlm archives to Mbox then that can be used as the basis for the Mailman archive.

http://wiki.list.org/DOC/How%20do%20I%20import%20an%20archive%20into%20a%20n...

Yup, this is similar to what I did. I recommend running cleanarch on that mbox before importing it, to ensure that it is ok. I took the second option in that FAQ, as it was a new list. Copy the Mbox file into the private directory after running it through cleanarch, then run the arch command to generate the HTML archives for the web interface.

Andrew.

Before going ahead, there is one thing I'm curious about as I don't understand it. Please, why does the path to the mbox file include <listname>.mbox twice? Here...

http://wiki.list.org/DOC/How%20do%20I%20import%20an%20archive%20into%20a%20n...

It reads...

Thanks Andrew and Mark! As a general rule of thumb, I usually avoid to reply to a message without reflecting for some hours on its content! Sorry for asking things with an obvious answer: I was using a sftp client to access /private and didn't realise that there is a folder, then a file, with the same name! listname.mbox. And thanks for the explanation!

Yup, the file needs to be called listname.mbox in the directory ~/archives/private/listname.mbox. So for example, to copy the mailman-users archive into your home directory, assuming Mailman was installed in the default location, you would enter a command like:

cp /usr/local/mailman/private/mailman-users.mbox/mailman-users.mbox ~

That would give you a file called mailman-users.mbox in your home directory with all the archives in mbox format.

If your list is new then after running cleanarch on that mbox file, I would copy it to ~archives/private/listname.mbox/listname.mbox, ensure perms are correct by running check_perms, then run arch with the wipe parameter to build all the HTML indexes for the web pages.

If you have a list already, I would stop Mailman, then cat the mbox file in place at the location ~archives/private/listname.mbox/listname.mbox to a copy of your converted archives. I would then run cleanarch on the resulting file, then put that in place in ~archives/private/listname.mbox/listname.mbox before checking perms and running arch with the wipe parameter.

Hope this clears things up for you. Andrew.

It worked! Thank you very much! I've learnt a lot, about a lot of things! Together with a great programe I've discovered a great community. Who knows? Perhaps in the future I'll be able to contribute in any way :-) Here we have our first "complete" list by consolidating former ezmlm managed contents with our brand new Mailman list with the same name...

http://lists.idisantiago.es/pipermail/r.users/

Still, I've a doubt about the syntax of Mailman commands. I do need to do...

[root@idis2 r.users.mbox]# cleanarch <r.users.all.mbox> r.users.all.clean.mbox

While <> are not required in command arch...

[root@idis2 r.users.mbox]# arch --wipe r.users r.users.mbox

If I don't use <> to enclose the input file name in cleanarch, I get the help page!

Usage of both commands as per their help pages are close to similar...

Usage: cleanarch [options] < inputfile > outputfile

Usage: /usr/lib/mailman/bin/arch [options] <listname> [<mbox>]

Also, arch alone shows its help page whereas cleanarch alone do "nothing". Those usage lines and command behaviour aren't to consistent, are they? Could this behaviour be caused by my local configuration?

Thanks!!!

You are not 'enclosing' the input file name in cleanarch with <>. cleanarch reads the input mailbox from stdin and writes the output mbox to stdout. You are actually saying '<r.users.all.mbox' which redirects stdin from the terminal to the file r.users.all.mbox and '> r.users.all.clean.mbox' which redirects stdout from the terminal to the file r.users.all.clean.mbox.

Note that you didn't need to do this as the <http://www.arctic.org/~dean/scripts/ezmlm2mbox> script already writes a 'clean' mbox.

On the other hand if you give a second argument to bin/arch, it assumes that is the mbox. It doesn't read stdin in any case and writes various progress info to stdout.

...

Usage of both commands as per their help pages are close to similar...

Usage: cleanarch [options] < inputfile > outputfile

This means use shell redirection to read the input from inputfile and write the output to outputfile.

...

Usage: /usr/lib/mailman/bin/arch [options] <listname> [<mbox>]

Here the notation <listname> means that is a variable to be replaced with the actual list name and [<mbox>] means that <mbox> is a variable to be replaced with the actual mbox, but the [] mean it's optional - if not provided it is computed as archives/private/<listname>.mbox/<listname>.mbox.

...

Also, arch alone shows its help page

because arch without at least a <listname> argument is invalid

...

whereas cleanarch alone do "nothing".

Actually cleanarch alone is valid and both reads its input from and writes its output to the terminal. That's why if you type just 'cleanarch', it doesn't return immediately to a command prompt but waits for input from the terminal.

Consider

mark@msapiro:~$ /var/MM/21/bin/cleanarch

• it's waiting for input- I type From someone
• it responds

• to stdout, and Unix-From line changed: 1 From someone
• to stderr. then I type ^D (control-D - end of file) and it responds 0 messages found
• and exits.

...

Those usage lines and command behaviour aren't to consistent, are they? Could this behaviour be caused by my local configuration?

...

From someone

No. They are caused by two different programs written by at least two different people. So yes, they aren't exactly consistent, but if you understand the different commands and the shell redirection, it may make more sense.

True, cleanarch could have been written to require an input file argument instead of using stdin, but using stdin and stdout makes it easy to insert it into a pipeline of commands as in for example

ezmlm2mbox [-d] ezmlm_dir | cleanarch | arch --wipe <listname> -

except for the fact that arch doesn't read its stdin even if the conventional '-' is used as the mbox file name.

No, you don't have Maildir, at least not "Maildir" as most of the Internet understands it. Here's what Dan Bernstein (the inventor or at least popularizer of Maildir) says:

Can a maildir contain more than tmp, new, cur?

Yes:
.qmail: used to do direct deliveries with qmail-local.
bulletintime: empty file, used by system-wide bulletin programs.
bulletinlock: empty file, used by system-wide bulletin programs.
seriallock: empty file, used to serialize AutoTURN.

"Lock" -- no, this isn't Maildir. The whole point of Maildir is that you don't need locks because reading and writing are done in different directories, and changes happen atomically. (This can even work with editing.)

Within /archive, there are two folders, 0 and 1, with a number of files, each of them containing one message, and an index file.

Please, does this made sense for you?

I don't recall anything like that. Please try to find an explanation of the structure in the system documentation, or ask the vendor. However, since you think they're "Maildir", probably what is meant is that they have a structure that is one message per file rather than many messages per file. You probably just need to figure out how to get the order of messages right, then concatenate the messages.

Most likely, all you need for each list are the archive folders and the single messages, and maybe the index file will be of some use depending on what it contains. If your documentation and/or the old vendor are of no help, see if you can find a whole message file you can send to us *as a file attachment* -- we want to see what headers are included (it probably doesn't really matter, though, except for the "Unix From_" which they probably don't have). If for privacy reasons you don't want to broadcast any message on a public mailing list, you can send it to Mark and me personally. Also it may be helpful to figure out the rule for the folders whose names are numbers: are they the leading digits where files are named 000 to 999? Are they months? Years? etc.

Am I completely lost?

No, of course not. Just don't delete anything until you're sure the new system is working. I did qualify everything with "probably", it may take a couple of guesses to get it right. :-)
