I see the problems with

ii  exim4-daemon-light            4.94-19                        amd64        lightweight Exim MTA (v4) daemon

I checked the PTS and it seems, that this package might have
just been released around the same time (no timestamp given)
than the 21nails patches.

[2021-04-26] Accepted exim4 4.94-19 (source) into unstable (Andreas Metzler) 
[2021-05-05] exim4 4.94-19 MIGRATED to testing (Debian testing watch) 

I did not verify if exim4-daemon-light for bullseye is REALLY
patched or still vulnerable, which it should be (unless Debian
has broken the disclosure embargo).
