Mails containing plain text are empty

[vmario89]

Hi,
pushing emails without html body like "echo -e "ok" | mail -s "from-test@abc.def" theTarget@ma.il" are going to be empty in Matrix

another example:

As you can see the content is not the plaintext, instead it's just "zero" - both on chat and on the browser message

additional notes:
reconfiguring production.yml to change messageFormat, fragmentFormat, skipDatabase, messagePlainFormat, fragmentPainFormat did not change anything. I played through with all possible variants. i think the message parsing itself is the problem here

hm okay had another try. i looked into sqlite database. the mail content is there. the $full_text_body is fine. i reconfigured production.yml to use
messageFormat: "$subject: Hier klicken, um die volle Nachricht anzuzeigen"
fragmentFormat: "$full_text_body"
messagePlainFormat: "$subject | https://red.redacted.de/m/$id"
fragmentPlainFormat: "$full_text_body"

in html body there you can find the "zero" i mentioned
it does always render "zero". - only some of the plain messages seem to work
