Trolls can wreak havoc by subscribing to one or more high volume mailing lists
on behalf of a target one. For example, someone could subscribe this list to
the Linux kernel mailing list. Everybody would see the confirmation message,
but by the time someone realizes the need to unsubscribe, the list will have
been flooded, thereby realizing the DoS.
Are there mechanisms to prevent that?
I've installed my reverting DKIM verifier. Today it failed on a specific
message which I also received directly. The reason it failed is the Subject:
field was rewritten like so:
Subject: RE: [dmarc-ietf] A policy for direct mail flows only, was ARC
Subject: Re: [dmarc-ietf] A policy for direct mail flows only,
was ARC questions
The message is tagged X-Mailman-Version: 2.1.29. Is it Mailman doing that
change? I found some code which may seem to be doing something like that in
rematch = re.match(
subject = subject[rematch.end():]
recolon = 'Re:'
It seems I have to save the subject if it matches that string, correct?
I am pleased to announce that with a week long delay from the planned date,
