Well, for instance I am subscribed to several
opensuse.org mail lists.
They are using mailman3/Postorious/Hyperkitty/.
When email appears from some posters with problematic servers, they
replace the "From" header:
X-MailFrom: ...@
opensuse.org
From: Some One via openSUSE Factory <
fac...@lists.opensuse.org>
Reply-To: Some One <...@
suse.com>

Cheers, Carlos.
