[LEDE-DEV] DMARC related mass bounces / disabled subscriptions

[Jo-Philipp Wich]

Hi list,

a recent mailing list post from a DMARC enabled domain caused a large
flood of bounces from various mail providers, causing an automatic
disabling of about 190 subscriptions [1].

I re-enabled those subscriptions manually so there is no need for
further action on your side.

In order to mitigate this problem in the future, I configured this list
to wrap mails from DMARC enabled domains into an outer mail using the
mailing list itself as sender [2].

Please excuse the inconvenience caused by this issue.


Regards,
Jo
