Hi,

Is anyone else receiving non-delivery report emails from
postmaster@ewetel.de for every email they post to debian-user? They
look like this:

    From: postmaster@ewetel.de
    To: andy@strugglers.net
    Subject: E-Mail Abweisungsbenachrichtigung / email bounce notification

It goes on to state that the message wasn't delivered because the
recipient's mailbox is full.

I've received one for every email I've sent to debian-user over the
last 4 days. Anyone else? If so, can you let
listmaster@lists.debian.org know?

Naturally, ewetel.de should be rejecting these messages inside the
SMTP connection if they can't be delivered to their user.

Failing that, they should be sending NDRs to the envelope sender,
which is the Debian mailing list software, which would then take
care of unsubscribing the undeliverable address.

It seems to have done the very broken thing of sending an NDR to the
from address. If that assessment is correct, Debian listmasters will
need to disable delivery to this subscriber manually.

But, possibly whatever problem it was has fixed itself by now. If
ewetel were ALSO sending an NDR to the envelope sender then the
subscriber would have been disabled eventually.

Thanks,
Andy
