Comment 3 for bug 266009

I am having a simlar problem. Mail comes in, but never goes
out to the list. Everthing is shunted. I found this "patch"
http://www.mail-archive.com/mailman-developers@python.
org/msg06317.html and applied it. Then I ran unshunt. That's
when this appeared in mailman/logs/error
