Problems with email digest

Every two or three times that I receive the email digest for this mailing list, I get a single text file attachment and the following message instead of a set of message attachments. Is this a problem with my mail server or the list server? This message uses a character set that is not supported by the Internet Service. To view the original message content, open the attached message. If the text doesn't display correctly, save the attachment to disk, and then open it using a viewer that can display the original character set.
