Hello
I use gmail, and seem to be getting email from this list. I wonder if it
is because I have it skip the inbox, and go straight into a different
label.
I think you are on to something: It could well be that there has been a shift
to using how the recipients organise their gmail (do you sort it into
a high value folder, do you reply to it, do you star it, etc, etc) as
a factor in the decision to reject email at the SMTP transaction.
That might explain why a small subset of gmail users still get to
see the DNG messages ... if the heuristics are local to a user.
Which seems reasonable, otherwise a spammer could sign up and superlike
the their own spam, guaranteeing delivery for others too...
Though I am not sure I should expend the energy to run some tomography on
these interactions, in order to discover the heuristics that
google actually uses - with apologies to the hitch-hikers guide to
the galaxy: As soon as we have an explanation, the system will be
replaced by an even more complex set of rules.
What it does seem to mean is that gmail users are likely
missing some legitimate messages completely - without even a
trace in their spam folders.
I suppose that is just another instance of the Availability vs
Integrity vs Confidentiality Tradeoff that underlies most
of Computer Security... though I for one like to make that
call myself rather than having some AI try infer that from
my mail reading behaviour.

Not for to use this list but i do have a gmail account as spamcatcher
for a publicly visible mail address. I never use the web interface
though but use Thunderbird to handle that account. So i do not see fancy
lines or high value folders or am using stars. So far Google does handle
spam correctly and I do not have to search that often in the spam
folder. I recommend this for all gmail users.
I do run my own MTA (three of them actually) and noticed a rejection by
gmail the moment I got IPv6 and forgot to set reverse DNS for it. So
rDNS is a thing for gettingaccepted by gmail.
Grtz.
