By popular demand, Jay and I have set up demime on the ClassicCmp server, and all posts are being filtered through it. From here on out, all posts you get from CC will be in plain text, with no attachments or HTML. If you send file attachments, they will be removed from your post. If you post anything other than plain text messages, plain text will be extracted or rendered as appropriate. Even HTML-only or RTF-only mail is rendered into plain text. Demime tries very hard to convert your post into plain text, but if it simply cannot, it will bounce your post.
