In a mailinglist it seems some mails are not forwarded to a member, but is listed in archive in hyperkitty. That mail did include a PDF attachement, but HyperKitty does not list any attachement.
There are two issues here. Why wasn't the message delivered to list members?, and why is there no attachment in Hyperkitty?
For the first issue, you need to examine mailman.log for the time of the post looking for errors and tracebacks. Also, the MTA logs may have useful info if the messages were sent but not delivered.
For the second, there are many content filtering settings not (yet) exposed in Postorius. These include filter_extensions, filter_types, pass_extensions and pass_types which control which MIME parts are removed. For a newly created Mailman 3 list, these four settings are empty, but importing a Mailman 2.1 list will set them according to the corresponding MM 2.1 list's settings.
All I found was "convert HTML to plaintext", but does this setting remove attachements?
It would only affect HTML parts, not pdfs.
Is there any generel documentation about attachement processing in MM3?
<https://mailman.readthedocs.io/en/latest/src/mailman/handlers/docs/filtering.html>.
I would like this mailinglist to accept mails with attachements, send it to the members and archvie the attachments in HyperKitty, to.
You can set Settings -> Alter Messages -> Filter content to No in Postorius to not do any content filtering at all. This will override the Collapse alternatives and Convert html to plaintext settings and pass the message without removing any MIME parts.
But, I think you must have other issues, either with this mail in particular or in general as evidenced by the mail not being received by list members.
