Re: [mailop] GMail 550 5.1.1?

[Brandon Long via mailop]

I was the TL of the second version of groups that added the improved web
archive and mailing lists, and ensured that usenet was well supported at
the time... and continued to maintain the incoming and posting servers
until a couple years back.  The groups usenet archive is still available as
a web archive and in search, though I've felt the search isn't as good as
it used to be... or at least doesn't seem to surface usenet like it used
to.  It's a smaller and smaller subset of the groups archive over time, so
maybe that's natural.

If there were other requirements for our handling of the archive, no one
made me aware of them... but I did join well after that acquisition and the
first groups search.

Ah: he *sent* Usenet out that way.  Got it.

FWIW, Andy Tanenbaum got back to me before I could rig in my antenna,
and tells me that his quote wasn't conditioned on any particular situation.

I dunno; I got mine -- thanks to Spaf, then at GATech -- over a 1200bps 
modem from USF.  :-)

Henry's was, I think, the biggest contribution to DejaGoo, but there were, 
IIRC, hundreds, and at least a few of them (possibly including utzoo's) were
conditioned on Google's (not really fulfilled) promise to aggregate it *and
make all of it available in a useful form*.

It's been 30 or 35 years, the possibility I'm misremembering some of it
does exist.  But I have a bit set -- and it's a pretty large bit -- that
Google promised some stuff that they never delivered, and people depended
on it.

There is some confusion here.  Lyndon is correct as for Australia.  Jay 
has it backwards.


The Australia link was what I was referring to.  Which was connected 
with NASA, and I believe Eugene Miya was involved.


That's what the quote was referring to, and may have even been from Tom 
- he is that sort.  However:


Henry (who I was in CompSci with at UofT and knew him quite well)

LSUC, York et. al.


[I then ended up in BNR, which for a while was one of the largest Usenet 
transit sites in the world.]


Tom's connection with magtapes vis-a-vis Usenet that Jay is referring to 
is the *archive* of the Usenet traffic that Henry kept on tape, and gave 
to Dejanews.

The original quote, IIRC, was talking about Henry Spencer at UT Zoology, who
got Usenet that way for a while.

I could tell you for sure, but Google never released the DejaNews corpus as

As I would have thought was obvious, the refund was to third parties
who are neither customers nor even Gmail users complaining that Gmail
didn't handle the mail that they sent to Gmail the way they wanted.

If I were paying for Gsuite I would expect a refund but that is a
totally separate issue.

For a couple of years, the Usenet link to/from Australia were magtape 
exchanges on a routine NASA flight out of, if I remember right, NASA 
Ames.  It was piggybacked on the shipment of data to/from joint 
NASA-Australia projects. I used to correspond occasionally with the guy 
involved in doing that.


This would have been from the era when 9600baud and partial T1s via UUCP 
were the bees knees.


You'd ask a question of someone in Australia, and you generally had an 
answer within 3-4 days.


Which led, in part, to the old meme "never underestimate the bandwidth 
of a shipment of magtapes".


Tho, I suppose you'd be hard pressed to do that today even with LTO-6. 
Not that Usenet is that big today.

The 250 code you refer to is the SMTP handshake and says only that the
mail was transferred successfully between two mail relays.  It's no
different than sending an ACK after receiving a FIN in a TCP
connection.  It's a transmission protocol state transition indication.

The SMTP response only applies to MTAs, mail transfer agents.  It does
not apply to MUAs, mail user agents.  There is no ability and has
never been an ability anywhere at any time to know that someone has
read the message.

Plus the SMTP protocol has never tried to be an end user visible
protocol.  Which, if implemented over Avian Carriers, might be
unappealing to the consumer.  Even if the cost is only bird seed.  The
diagrams in RFC 2549 I find the most enjoyable.

In my experience of investigating a few of these in detail, this is not
actually the case. Instead, what happens is that the Gmail interface
makes people unable to find it, because users don't realize that
searching doesn't search the Spam or Trash folders, *even with the "All
Mail" option selected*.

If you can reliably get people to follow the instructions here, they
usually find it:

With Gmail's self filtering folders, for many smaller hosts the chances of a 
message which gets a 250 response code being "received" (reach the eyeballs of 
the intended recipient) is lower than not. So 250 says more about Gmail 
internals (e.g. the message wasn't rejected by the first gatekeeper) than it 
does about successful delivery. End users still complain that messages weren't 
delivered, and we have to investigate each time.

That's nice to know, but the fact is that messages accepted by Gmail sometimes 
disappear without a trace. No doubt that the systems involved on your side are 
massive and complex, but that shouldn't be our problem as indie hosts.

So, returning 250 OK when delivering a message to spam is bad form now?  Or
a 4xx response to potential spam that you're not quite sure about?



Also, there is no provision in our spam system for dropping mail, it's
reject, deliver or bounce...
I guess workspace does add administrator actions like admin quarantine or

It seems to come in bursts. We are ignoring the 550 and queuing.  Earlier 
nothing was queued and now about 500 messages are in the queue but some new 
mail is being accepted.

 GMail is still listed as having issues: "We're investigating reports of

I think it's pretty obvious that whatever failed was not something
they expected to fail, so it's not surprising that it didn't fail in
the optimal way.

I'm seeing other odd effects. One of my users has her Gmail account
set to pick up her mail from my server. That stopped at about 530 AM
EST and never resumed. We scratched our heads, I suggested she delete
the pickup rule and add it again, which worked.

R's,
John

Our customers are beginning to see these today.

When I looked at

earlier this morning Gmail didn't acknowledge it

but I now see they are admitting to having a problem again as of a few 
minutes ago.

Gmail was (and still is) sending out false ‘unknown address’ responses. One 
person ever reported their own (working, logged into) gmail address bouncing.

That assumption is called into serious doubt by the fact that GMail is 
replying with a very specific extended response code which states the

For information this didn't last the 1 hour and 10 minutes logged in the report 
https://www.google.com/appsstatus#hl=en=issue=1=109f5878e60fdfb3c0f64fc9b81752e1
 , at least for several senders in Europe. Maybe you're luckier in the US.

It seems to be calm at the moment I'm writing this, but we already had calm 
moments today, followed by huge spikes again. 

Note that Gapps domains are also impacted.

But I assume the mailserver didn't get a *positive* reply "yes, it is
confirmed that the user DOESN'T exist" but simply wasn't able to connect to
the database and verify whether the user exists or not.

That's exactly a situation where 4xx should be used.

With all the services being down at the same time I am expecting it to
be an issue with the central "user database" itself. In that case their
mailserver simply didn't know users existed.

Many Google services including Gmail, Google Drive, and YouTube have 
been having issues today according to Outages mailing list. Though some 
are reporting restoration this could be lingering problems.

We are seeing huge spikes in those codes as well.  Some testing shows that
valid addresses are getting that response intermittently as well.

Yes, it started about an hour or so ago for us.  Accounts that had
delivered yesterday or even earlier today in some cases are now seeing that
error.
