If the person replying is using a text only MUA and/or has turned off rich 
text E-Mail, that will also strip off the HTML.  Actually many people do that, 
so depending on "rich text" features is not really very reliable and not 
something you can always rely on.

Also, please provide more detail as to what you mean by "the initial
message shows all correctly, only when we reply, it strips the
highlighting."

If you are saying that an initial post in a thread as received from the
list includes the rich text formatting, but a reply to that post that
quotes the rich text does not include the formatting, then this is not a
Mailman content filtering issue after all. It is the MUA doing the reply.

I wish I can attach the screen capture to this email, but your system 
doesn't accept it.
Is there anything else I can check, note that the initial message shows 
all correctly, only when we reply, it strips the highlighting.


Thanks,

I am doing the same highlight here to see if it will work for this group.


This list employs content filtering and among the options is Collapse
alternatives which is set to Yes.

That means when you compose your "rich text" message in your MUA, and
the MUA creates a message with a text/html part for the rich text and a
text/plain alternative part, the list will discard the text/html part
and keep only the text/plain part which doesn't have all the rich text
formatting.

You can adjust your list settings to not filter content at all or to
accept both text/plain and text/html MIME parts and to not Collapse
alternatives and not Convert html to plain text to avoid this, but the
HyperKitty archive will still display only the plain text and the raw
html will be stored as an attachment.

"Highlighting" is a function of non-plaintext email, most often HTML in 
the modern world but also sometimes other proprietary formats (e.g. 
older Outlook) or other "rich text" formats that have lost the 
competition to HTML, such as the "text/enriched" format. Most mail 
composers using HTML in email use a "multipart/alternative" structure 
which includes both a HTML version of the message and a plaintext 
version, so that mail readers can display the mail even if they do not 
support HTML. For a variety of reasons, some mailing lists are 
configured to strip out the HTML part of multipart/alternative messages. 
Many users (including myself) also preferentially only display the 
plaintext version of multipart messages and so only reply to what is in 
that part. Because any "highlighting" is only present in non-plaintext 
email, lists and users who stick to plaintext do not see or preserve 
that highlighting.
