I have pretty much no faith at all in the common sense of judges when
it comes to technical issues indeed, and good reasons for doing so.
It may be a German issue, but I doubt it. I could imagine very well that
a spammer using vacation based opt-in does not get in serious trouble
for a year or even longer over here. Hell, even without that he may
not get any trouble. All you can do is subscribing his administrative
addresses to his own list, among others. :-( But that's another point.
yes, I don't think fixing the German judiciary system is practically
possible for Sieve :-)
First of all, users will be annoyed by being subscribed to a list, and
be very annoyed if subscribed to multiple lists. Vacation MUST contain
heuristics to lock out mailing lists and their owner/request addresses,
but there is no safe way to detect them. Subscribing typical users to
old-style lists without web interface causes them grief to no end and
there are enough idiots around having fun doing so.
there are plenty of lists which don't require confirmation messages,
either. Sieve can't fix these. if there are lists which don't do
proper checks to see if the confirmation checks are automatically
submitted, Sieve can't fix these either.
the vacation extension should leverage whatever mechanisms other RFCs
specify for recognising automatically submitted messages. this includes
RFC 2919 (List-Id) and RFC 2369 (List-Help etc.), but not heuristics
like "if the local part of the sender address starts with 'owner-' or
ends in '-owner'". making such heuristics standard is work for a
different group, IMHO.
