After investigating a bit, it looks like a problem with HyperKitty
not being
able to export messages with attachements properly. The bug has been reported
in issue #252[1] and fixed in PR !182[2]. The fix was included in HyperKitty
v1.3.1 released in December 2019.
The HyperKitty currently installed on the DebOps mailing list server is the
one included in Debian Buster, v1.2.2. Newer version which includes the fix
(v1.3.2) will be included in Debian Bullseye[3].
Thanks for this crystal clear report. I suppose that waiting is the only
viable option here.
