Others have already mentioned the issues with the missing In-Reply-To header  
etc. The most problematic thing seems to be the inclusion of NUL-characters  
in the lines of form:

> *	From: Reco  recoverym4n@enotuniq.net

|                  ^                        ^

The indicated columns (with `^`) seem to appear as tabs, NUL bytes or pad  
bytes in other mail user agents. It is problematic that these occur in your  
e-mails because they cause the mails to be displayed wrongly for some users  
(some clients see only the begin of line until the first NUL, others only  
the begin of message until the first NUL).

Check the source code of
https://lists.debian.org/debian-user/2019/07/msg01178.html
to find out that there are unexpected NUL-bytes:

$ wget -Otest.html https://lists.debian.org/debian-user/2019/07/msg01178.html

I am using a niché e-mail client as well, so I wish you the best of luck in  
fixing that issue...
