Same problem here. What is happening is that anyone who sends mail with html code has the code show up because the daily digest is text based. Also, I notice that some include images in the e-mail. Images will include about a foot of code. The solution is if all messages were transformed to text when posted in the daily digest. Without destroying the experience for those who use the daily digest, I know this will be difficult. However, I know it's possible because Yahoo group digests don't include the html.

Hello to Whoever asked about our experience with the new format,
I have subscribed to the digest and find that there is so much imbeded code
that to get from one post to the next is very confusing visually. I would
like to change either to recieve the posts individually or to some format
that will get rid of the code, if such a thing exists.
