[Mailman-Developers] senddigests -> LookupError: unknown encoding

[VLists.Net Support]

A couple days ago our digests stopped going out automatically.  I forced it
to run this morning via a special cron entry and received the following
report.  Can anyone give me a clue as to where to go find out what's
happening?    Thanks.

Traceback (most recent call last):
