I have been getting the following messages in /var/log/maillog

I'm subscribed to the word-of-the-day list from dictionary.com. I'm sure that courier is correct in saying that their list server is sending malformed messages. However, I can't control how they send it, I just want to keep getting my word of the day. Is there a way I can disabled this check and have courier deliver the message even though it does not have the required MIME?

Thanks, Ryan
