Nearly-spam mail causes unsubscription threat

["Thomas Schmitt" <scdbackup@gmx.net>]

Hi,

i just received a message from the list server that my mail provider
GMX has rejected a spam message which the Debian list allowed to pass
by a tiny not-spam margin.
From this quite unsuspicious situation the automat of Debian Listmaster
Team derived the threat to unsubscribe me.

I see the potential for a bounce troll, like we had a few years ago.
(Whenever one of us posted to the list, the troll faked a bounce from
our mail providers.)

Do other experience the same ?

(I would propose that list server shall please refrain from
unsubscription threads if the mail in question gets a near-spam score in
the Debian list system.)

Details:

The list server quotes a reply from the GMX mail servers.

The web says that DATE_IN_FUTURE_06_12 from Spamassassin means that
the mail's Date is 6 to 12 hours in the future relative to the time it
was received.

My provider takes more offense:

  https://postmaster.gmx.net/de/case?c=r0701&i=ip&v=82.195.75.100&r=1MYcpl-1siPQU12EF-00K6HO
  "Die Zeitangabe im Date-Header weicht zu stark von der tatsächlichen
   Zeit ab."
  = "The time stamp of the Date header deviates too much from the
     actual time."


Have a nice day :)
