It sounds like they are multipart/alternative components. You should understand what this means, and be able to identify the difference between this and an attachment (which could be plain text, an HTML file, or something else). You need a MUA or other means that allows you to look at the message verbatim, or at least at its headers (message and MIME).

"multipart/alternative" means the same information is being presented in different ways (typically as plain text, and as HTML), and the MUA is supposed to choose the preferred one for the user.

I think the goal for 2.0 is to allow configuration to set either text or HTML as preferred, and have hypermail process accordingly?

The question of how to treat an HTML *attachment* is a different one, and I have requested that such an attachment not be brought inline. Daniel's been working on making this a configurable option, also.

Simply bringing an HTML document into the middle of the larger hypermail HTML wrapper has a number of difficulties inherent in it - given the wide range of proper, improper and extended HTML that's floating around. For that matter, similar difficulties arise in dealing with HTML information given as an alternative.
