Actually, further testing of this scenario shows that Mailman is likely
responsible for the mis-encoding as well. Once I realized the key was in
providing the poster's real name from the list's membership, I was able
to duplicate the issue including the mis-encoding.
So I don't need to see any further samples, and I have developed a fix.
The basic fix is very simple. In Mailman/Handlers/Cookheaders.py around
line 155 are the lines:
change_header('From',
formataddr(('%s via %s' % (realname, mlist.real_name),
mlist.GetListEmail())),
mlist, msg, msgdata)
Immediately before the change_header insert (indented the same 8 spaces)
realname = str(uheader(mlist, realname))
which will RFC 2047 encode the realname if it contains non-ascii.
This is now reported as
<https://bugs.launchpad.net/mailman/+bug/1536816> and the fix will be
committed soon.
