Ho scritto ai gestori del listserver OSM (mail...@openstreetmap.org) il
24/12 e risollecitato oggi ricevendo finalmente una risposta da Tom Hughes.
In sintesi non ritiene opportuno effettuare cambiamenti al list server
perchè questi "maschererebbero" l'email del sender.
Ergo... ci teniamo il problema e lo bypassiamo (per chi ha gmail.com) con
il workaround già discusso.
Qui di seguito per completezza lo scambio di mail.
Ciao

Hello again,
unfortunately I did not received any kind of answer about the

mail, so I wonder if this mailbox is still being monitored.
If so, please let me know.
Thanks

It is, yes, but you sent your previous mail at 5pm on Christmas Eve so
it's hardly surprising that it got overlooked...
The short answer is that what your email provider is doing is broken as
it breaks (as you have discovered) all email forwarding including email
lists. It is foolish to believe that just declaring that the world should
change the way it's been doing email forwarding for thirty years is a
feasible way to proceed.
I have no idea if the version of mailman we're running even supports
the option in question, but even if it did I wouldn't want to turn it on,
because it breaks the mailing list by hiding the true sender.

Subject: DMARC issue
To: mail...@openstreetmap.org <mailto:mail...@openstreetmap.org>
Hello mailman admin,
I'm an OSM contributor of the Italian community and I'd like to
report
an issue we're experiencing on talk-it mailing list.
Some mails coming from the Mailman server are being classified as
spam
by some providers like Google and this especially happens with
senders
hosted on libero.it domain which is rather popular in
Italy.
In my understanding the problem lies in the p=quarantine DMARC
policy
set by libero.it admins, which triggers Google spam
engine after SPF check failure due to Mailman changes on mails
attributes.
I believe that DMARC is used by a lot of mail providers and the
issue
above could be a concern if they begin to adopt policies different
from
p=none.
I wonder if you are already aware of this issue and, in the case,
if you
evaluated the implementation of the Mailman features that allows
DMARC
mitigation.
Thanks for your attention.
Best regards
Andrea Albani
