Debian 9 ships with mailutils 3.1 whereas Debian 10 ships with version
3.5.  What you observe is the effect of the bug 54992, introduced in
version 3.4.  See https://savannah.gnu.org/bugs/index.php?54992 for the
details.

The bug was fixed on 2019-12-15.  I haven't had enough time to roll out
a new release since then (though I hope to do so soon), so the best
course of action would be to recompile mailutils from Git HEAD.  Drop me
a note if you need any assistance with that.

Regards,
Sergey
