Not, but I can sanitize it and share it if needed... however, I
have it in this regard just like you.

Yes, Gmail. But I don't see the ugly cuts in the middle of a
sentence since I use format flowed in mu4e (I don't use gmail web

Just to add some references, Adam Spiers in github said: I've
linked to this FAQ from
https://www.emacswiki.org/emacs/FormatFlowed
In that wiki there is a link to [[... mail clients such as Gmail
don't handle it
correctly][

which this issue is explained.
