Look at the message (bin/show_qfiles
qfiles/shunt/1197373305.4631159+54681260563e1d1577b352329843c2fa738ba81.pck).
I think you will see an RFC 2047 encoded Subject: header. I.e.
something like
Subject: =?iso-8859-1?q?this=20is=20some=20text?=
except the characterset instead of being like the "iso-8859-1" in this
case, will literally be "unknown".
Some MUAs will create such an encoding with character set "unknown" or
"unknown-8bit" when the subject contains 8bit characters and the MUA
doesn't have a context to know what the character set is.
If this is a recent Mailman, about a dozen lines into the definition of
process() in Mailman/Handlers/CookHeaders.py you will see
if not msgdata.get('isdigest') and not fasttrack:
try:
prefix_subject(mlist, msg, msgdata)
except (UnicodeError, ValueError):
# TK: Sometimes subject header is not MIME encoded for 8bit
# simply abort prefixing.
pass
If you change the 'except' to
except (UnicodeError, ValueError, LookupError):
and restart Mailman, you can unshunt the message and it will be
processed without prefixing the subject.
