Maybe a python version? What is really strange is that it works inside
the archiver.... I tried to NOT use email.message_from_file (so use
directly StringIO on sys.stdin), and it worked fine. In fact, the
error was that "Message doesn't have "tell()" method"...

Another error was really annoying : ALL worked. almost. I couldn't do
my mlist.Save(), as there was an error for the lockfile.

I did :
mlist = MailList.MailList('toto', lock=False)
# other code

-> crashed. After poking into MailList code, I saw that it refreshes
the lockfile. Commenting out this line made it work again.... more or
less : message was in mbox, but wasn't in pipermail archives....

Poking on the Net, I found this post
http://www.mail-archive.com/mailman-users@python.org/msg47499.html you
answered some months (well, years) ago. I tried this way :
applying the patch, so that it uses mailman internal archiver, and it
calls my indexer right after.
That's not really clean, it's not really a portable way, but it works.
The fact that I have to patch a file from mailman package annoy me a
bit, but... I didn't have any success with the ways you showed me :(

To be honnest, maybe I'll try to put a handler (like XapianIndexer.py)
for this. As I saw how to debug my scripts (thank you for the tip), I
guess it would be the best way, instead of patching a code (which will
be overriden on the next update).

Or maybe there's a variable in mm_config (or defaults) which tell
mailman to call a script after archiving ? I didn't see such a thing,
I guess that's the role a the GLOBAL_PIPELINE and its handlers

Thank you for the time you spend on my problem.

Best regards,
