Fwd: [Mailman-Users] shunt messages

[Nicolas Bertrand]

OK... Just found that post in the mailman-developers list that did the
trick:

http://www.mail-archive.com/mailman-developers@python.org/msg06317.html

"Barry, as was noted in a private email to ya - the problem was solved
with
the following patch (courtesy of Mohammed Elzubeir),

UTF-8

                 except (UnicodeError, LookupError):
                     t = t.encode(lcset, 'replace')

once we applied the patch and 'unshunt'ed everything went through.  We
did have a couple of messages with no Mime and Content-Type headers
(which are legal to have) and those seemed to have caused the problem.
A null charset within mailman caused our problems it seems and that
potential corner-case needs to be designed for.  As for a sample - I
tried mailing the affected list a simple "test" from this yahoo
account and it got shunted (as noted there is nothing peculiar about
the messages - mailman simply got into a state/setting where it
started
shunting everything -- Larry Price notes a possible means to get into
the 'state' above).  And again, I really don't think it was/is a
configuration/installation issue since the other 12 lists work without
any complaints and/or problems."


Cheers,

Nic

Hello,

We are having some serious problem with a 2.1.2 mailman install. Some
messages get transferred to qfiles/shunt and stay there forever. I am
calling on your help on this one. 

I understand from previous mailing list posts that the shunt directory
is used by mailman if:
   o messages are too large to get delivered
   o bug in mailman
   o problem with python installation
  
The original error message (in logs/error) was indicating some problem
with the 'strptime' module:
This was confirmed:
python
Python 2.2 (#1, Aug  4 2003, 14:00:57) 
[GCC 2.95.2 19991024 (release)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> time.strptime
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'module' object has no attribute 'strptime'

In the hope of remedying this, I have installed python 2.3
Python 2.3 (#1, Sep 17 2003, 21:23:32)
[GCC 2.95.2 19991024 (release)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> time.strptime
<built-in function strptime>

As you can see python is now happy with the time.strptime module.

I then proceeded to reinstall mailman. All seemed fine. I then
proceeded to unshunt the messages... In vain. They come back to the
shunt directory.

However, the error is  different:

Any ideas?
