That’s an issue related to mime-multipart support.  GUI oriented email readers (for example) prefer the HTML part, while text oriented email readers prefer the text part.  It used to be the case that each type could be configured according to the user’s preference, but I’m not sure that’s common now.

  To address your question directly, unless the mailman3 is configurable to do both, a decision would be required as to which to use (assuming the default to text isn’t the only option).

All,


The web interface for the new mailman version is at https://mailman3.common-lisp.net/postorius/ for mailing list administration and https://mailman3.common-lisp.net/hyperkitty/ for the archives.

Let me know if you find irregularities or have other remarks.

I checked the recently moved cmucl-cvs archive.

It looks as I would expect. The only thing that I wish it did is show the HTML version of the mail instead of the plain text since I’m using a browser to view the archive. I can scroll down to the bottom of the message and view the attachment that contains the HTML version, so at least it’s there. When I read the messages (sent to the list and not the archive) with gmail (or Thunderbird or GNUS), I see the html version of the message.

Not a big problem if this is not easy to do. The info is there if I really want to see the html version.
