I have the same problem with the difference that the mail body is added as an attachment too. This only happens if using mail with attachments as descriped above.
I think this problem is solved from mail --version 3.9-7 upwards and related to this debian bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=940249 which refers to https://git.savannah.gnu.org/cgit/mailutils.git/commit/?id=3a15565050 From my point of view, this is an important bug, because an email with text and attachments are quiet common and Ubuntu 20.04 is a LTS version.
