You have two choices. You can set Content filtering -> filter_content to
No, or you can set filter_content to Yes and set the following
You may also want to add some "rare" pdf types like application/nappdf
and application/x-pdf and possibly limit image types to, e.g.,
image/jpeg, image/png, image/tiff depending on what you want to allow.

Pipermail doesn't do that. Non text/plain attachments will always be
scrubbed. HTML will always be HTML escaped unless you add
ARCHIVE_HTML_SANITIZER = 3
See the docs in Mailman/Defaults.py which say in part

The alternative is to use an external archiver such as MHonArc

Did you set scrub_nondigest to Yes? (The FAQ says be sure it's No), but
setting it Yes or not passing HTML at all are the only things that would

He'd be the one to change ARCHIVE_HTML_SANITIZER, but it's a global
setting and doesn't do exactly what you want anyway.

That search returns no results. and mail-archive.com is an archiving
service, not a list host, but you could archive your list there if you
like it better than pipermail.

I have no idea how difficult it would be to install Mailman 3 under
Plesk. Mailman 3 installation is non-trivial. According to
<https://wiki.list.org/DOC/Mailman%20and%20Plesk>, installing Mailman 2
upgrades manually is non-trivial - "It is possible to trick Plesk into
recognizing newer versions installed manually but it's not for the faint
The situation might be easier with Mailman 3 since Plesk knows nothing
You might want to check out
to see what Mailman 3's HyperKitty archives look like, but that list is
plain text only. There are other lists at
<https://mail.python.org/mm3/mailman3/>, but I don't know if any have
HTML in their archives.
