As this list drops HTML


Not exactly.

Quoting Baptiste Daroussin (Pos= tmaster Team): "=E2=80=A6 the mailing list engine will reject html= only email, html is fine as long at it is created with text/plain alternative. =E2=80=A6".

A screenshot of this e-mail, before sending: <https://wiki.freebsd.org/GrahamPerrin/em= ail?action=3DAttachFile&do=3Dget&target=3D2022-11-12+10.47+freebs= d-questions.png>. 

and non-text attachments lik=
e your .png,


freebsd-questions does accept non-text attachments such as JPEG and PNG.

Please see, for example, photo_2021-10-06_10-36-41.jpg (image/jpeg, Content-Transfer-Encoding: base64) within the original of <https://lists.freebs= d.org/archives/freebsd-questions/2021-October/000011.html>.

A more recent example: the base64-encoded image/png that's invisible at <https://lists.freebs= d.org/archives/freebsd-questions/2022-October/001986.html> is visible at <http://markmail.org/message/h5htrf2lolh5o52m>= ;. 

sending to desired recipient=
s cc: questions - as you did on this one - would have at least reached th=
em?

Does hackers@ publish and/or archive graphic attachments?


See for example <http://markmail.org/message/vxxhadn6j7lrfa46>= ; and the first reply. Both with PNG attachments, User-Agent: Alpine 2.20 (BSF 67 2015-01-07); Alpine.

Corresponding <https://lists.freebs= d.org/pipermail/freebsd-hackers/2019-December/055358.html> included a visible hint that there exists a PNG. application/octet-stream, so (for example) whilst the resulting attachment.obj is not visible as a PNG in Firefox, it can be opened with Okular, GIMP and so on. 

Your message (the .eml) refe=
rred to above did have a base64 text part.=20
Perhaps it would be better if the list software returned non-text parts, =
though it would get busy with HTML?

ISTR Mailman used to mention but then ignore non-plaintext parts. Still m=
issing Mailman functionality, esp. re archiving; I used to browse various=
 other lists quite often.
