Strictly speaking, openSUSE mailing list is also spoofing email
addresses as I receive something like:

from Amedee Van Gasse <amedee@xxxxxxxxx>
to opensuse@xxxxxxxxxxxx

While in reality I should receive something like:
from opensuse@xxxxxxxxxxxx
to al4321@xxxxxxxxx

You understand ?
If so, maybe we can use reverse DNS and compare that to the email
header "From: " address ?

No. There are legitimate reasons why the IP address won't match the header
"From: " address.
What reasons ?

PS:
This has become a general mail routing, mail spoofing and mail security
topic, not about Opensuse in particular. I don't know if we're still on
topic and if other list members are still interested.
Is there an off-topic mailing list that is better suited for this kind of
interesting treads?

This is because opensuse mailing list was under attack by spoofing spammers.
And we are defenseless...

Well, some professional can even send email from command-line,
effectively converting the PC into email client.
Unfortunately I can only use email-clients like Thunderbird or webmail.
