The preserved messages are in qfiles/bad, but you have a major
compatibility issue. I can't really tell in detail what's going on
because the ImportError is thrown diring unpickling, but somehow the
queue entry being processed by whatever runner this is has a reference
to an email.header object, but the Python processing this is using an
older email package that doesn't have that module, only email.Header.

The most likely underlying issue is this is Python 2.5 or newer, but
you have an older email package in Mailman's pythonlib. The email
package in Mailman's pythonlib is not compatible with the rest of the
Python library in any Python 2.5 or newer version.

If Mailman 2.1.12 or later is properly configured and installed from
source, it will detect that the system Python has an email package as
new or newer than 2.5.8 and will not install its email package in
pythonlib and will remove an existing pythonlib/email.

It seems that perhaps what you have done is upgraded the Python in an
older Mailman installation and not reconfigured Mailman.
