#264073 — Non-delivery reports from postmaster@ewetel.de

FromAndy Smith <andy@strugglers.net>

SubjectNon-delivery reports from postmaster@ewetel.de
Message-ID<HGkNX-arIn-7@gated-at.bofh.it>
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

I have not received a NDR for this user. I think I have used
debian-user recently enough that I might encounter one.

When I receive multiple NDRs like that, I forward it to the mailing
list administrator (along with the original message), and ask the user
to be removed from the list. The user can re-subscribe once they clear
up their issues. The list administrator can be reached via
<listmaster@lists.debian.org>.

Yep, I did do that, I just wondered if it was happening to anyone
else. 😀

Hello Andy,
I have received one mail like that when posting to the l10 list.
The mail appeared in the list in spite of that message. With further
mails everything has been back to normal.

Okay, thanks, glad to hear ewetel wasn't just objecting to my email. 😀

> The mail appeared in the list in spite of that message.

Yeah, that NDR is from ewetel.de for one of their own users, not for
the mailing list. It is broken for it to send such an NDR to the
poster. It should have gone to Debian's mailing list software, so
that the rejection could have been automatically handled.

It doesn't seem to be happening any more so perhaps it was, or the
Debian listmasters disabled the user's subscription.

Thanks,
Andy

Or the user deleted enough old emails that their mailbox is no longer
full, which just postpones the problem until the mailbox fills up
again.

Before posting the above I had reported the problem to Debian
listmasters, and they asked me to let them know if it kept
happening. It wasn't clear to me however if that meant they had
taken any action. It doesn't seem to be happening any more to me but
if it is for you, you should report this to
listmaster@lists.debian.org.

Thanks,
Andy
