Hi all,
today, all gmail users were unsubscribed from the mailing list, because we
have users who sends e-mails from domains with the DMARC policy reject (like
cirrus.com). The mailman counts those bounces and unsubscribe users who do not
receive those e-mails. The nice explanation is here:
https://www.linuxchix.org/content/mailing-list-changes
I can enable the "Replace the From: header address" in the mailman config to
"Munge From" like in the above example, but it will mean that From: will be
altered (see the explanation).
Another option is to disable the bounce check in mailman, but it will cause
that the "dead" subscribers are not detected anymore.
Any opinions on this?
